Six Lessons Learned On The Grass

Last Friday, while having my telescope set up at my daughter’s school, we saw what I believe to be a Falcon 9 upper stage venting excess fuel on its first orbit around after a Starlink launch from Florida. Tonight there was a very similar launch at a very similar time on a very similar mission, so about 80 minutes after the launch I sat out on my front yard with a camera for a while just in case it happened again. It didn’t. But there were still six lessons I learned.

  1. With the multiple flood lights set up by the new neighbor across the street, it’s tough to see anything more dim than a 737’s landing lights going into Burbank. DAMN! In the search for the Forever Home in the High Desert, I’ll have to keep that in mind.
  2. When it’s quiet, you can hear the train whistles from the Santa Susanna Pass, about two miles away as the crow flies. Funny, I would have guessed it was closer to ten miles, but Google Earth says otherwise.
  3. The rabbits out on the front lawn freak out when I go and sit down on the grass – that’s their grass and there was a lot of leporine side eye going on. I didn’t know I needed an invitation.
  4. In addition to the trains, there were repeated calls from what I’ve always referred to as a “night hawk” or “screech owl.” Turns out the latter guess was closer – what I’m hearing is the screech of a barn owl. Given the Great Horned Owls we hear almost every night, I guess I’m not surprised to hear another kind of owl around as well. But I’ve never, ever seen one, I just hear them once or twice a night, and several times tonight.
  5. The rabbits would be a lot healthier if they spent less time giving me the stinkeye and more time watching out for those barn owls.
  6. The sprinklers turn on at 8:00. With little or no warning. Good thing I’m wash & wear, even at my advanced age.

The Forever Home definitely needs to have dark skies, trains, owls and hawks, and probably rabbits. Although I suspect in that environment (and sort of here as well) the coyotes will be more of an issue for the rabbits than the owls and hawks.

No Aurora For Me

Another obvious bucket list item for me would be to see the Northern Lights or aurora. I figured I would need to book a trip to Iceland or Northern Canada or Alaska to see them, but tonight a huge CME (Coronal Mass Ejection) from the Sun has slamdanced the Earth and we’re getting the most vivid and widespread aurora in 50+ years. On social media there are amazing and detailed photos from places like Detroit, Chicago, upstate New York, and even as far south as Nashville and Ohio. Even further south, there are photos of the sky glowing red and purple from Miami, Texas, and Mississippi, and even Southern California. I saw one set of pictures from Thousand Oaks, which is only a dozen miles from here.

Here, I’ve been taking cell phone pictures and looking a couple times an hour all night, but with no luck. We have light pollution near the horizone and the Little Dipper, and some haze and clouds off to the north.

Straight overhead you can see the Big Dipper, which would look even better if I wasn’t too lazy to go get the iPhone tripod and use it instead of shooting these pictures handheld. But no aurora, no purple or red tint to the sky. And now the clouds have moved in here.

Maybe on the next once in a lifetime occurrance. Maybe that will either be stronger so that the skies light up even at 34º12’03″N, or I’ll be somewhere further north so that I can see them.

If you’re further north tonight, I hope you had clear skies and a great view of a colorful sky, excited by high energy particles and plasma thrown out from the Sun! Enjoy!!!

And please, everyone try to take a peek for aurora on Saturday and Sunday as well. This solar storm might be strong enough to last a couple of days. If at first you don’t succeed…

LOVE That BOOM!

I’ve been REALLY busy all day, a tight deadline looming.

On the one hand, I knew that SpaceX had a Vandenberg launch scheduled for tonight, and it was going to be right at sunset so it had a good chance of being spectacular, but then I got a notice that it had been bumped by a couple hours to 21:30-ish. I didn’t even know exactly what time, and I was TOTALLY heads-down in the deadline tasks.

Until, at about 21:45-ish, the wall and west-facing window in my office gave a good, sharp, shake and rattle from the sonice boom from the Falcon 9 that had launched and gone supersonic off of the Ventura coast about t6hirteen minutes earlier.

I’ve heard it before when I’ve been listening for it, but for some reason, when I was NOT expecting it, it seems so much louder and more distinct.

I love living “near” (100+ miles) a freakin’ spaceport!!!

More Boca Chica Photos!!!

I’m brain dead and burnt out. I’ve been to the dentist again, I have to go to the endodontist, they’re talking about multiple root canals in my future, and all is shit. So, since I shot HUNDREDS of pictures at Boca Chica a month ago, let’s look at more of them.

The Rocket Garden.

The launch site from the construction site.

That’s a freakin’ big launch tower.

The Starship booster was on the pad. The cloud is some sort of cryogenic fuel that was venting.

That’s the Quick Release connection. It moves over to connect to the top of the booster, and fuel pumps through it into the liquid oxygen and supercooled methane tanks. When the launch starts, it disconnects in just a second and pulls back away from the rising rocket.

Waaaaay off in the distance, about eight miles away, is South Padre Island, which is the best place to watch a launch from if you don’t work for SpaceX and can’t get onsite.

The “chopsticks” which rise up, spread wide, then close around the top of the booster to lift it off of the transport vehicle and up into position on the launch pad.

The space above the top of the booster is where the Starship rocket goes, also picked up and put into position by the “chopsticks.”

The “hopper,” the first test vehicle that flew and landed safely on its own.

The 2024 Total Solar Eclipse

Some days it’s better to be lucky than good. All week I was asking for a little luck, a break. When the time came and the celestial mechanics lined up while the crowd counted down, we were lucky.

As I said last Monday (see the other pictures from that day here), it was an emotional roller coaster ride all day long. It was completely overcast when I woke up, but clearing a bit by breakfast.

My son drove up from San Antonio (about 90 minutes southeast of Kerrville) and we stated the walk over to Louise Hays Park. It’s two miles, but most of it’s along a lovely nature trail along the Guadalupe River. We even spotted a herd of a dozen or so deer off in the bushes next to the trail. Lots of interesting birds and flowers. (Many pictures to use later…)

Louise Hays Park is an island in the Guadalupe River that’s been turned into a humongous community park. In the center of the park was a large stage and video screen and two NASA pavilions. All around the edge of the park were vendors and food trucks. It was a nice setup. I have nothing but nice things to say about the City of Kerrville’s program and preparations for this event. It’s a town of about 25,000 folks, but there were early estimates that they could easily get 250,000 people coming to town for the eclipse, if not even more. They were ready and it all went smoothly. The predicted clouds probably kept the crowds down by a significant factor. I would estimate that there were something like 50,000 to 60,000 folks at the park, but it certainly wasn’t 200,000+.

Soon after we got to the park and set up our cameras and tripods, we started cloud watching. Kerrville had 4:24 of totality, starting at 13:32. By noon things were looking sort of nice, maybe 50% cloud cover overhead, high clouds that were thin enough to see through, but with lots of low, thick clouds on the horizon all around.

At 12:14, the first partial stages of the eclipse started and everyone started using their eclipse glasses to watch as the moon started to cover the sun. There was a notable buzz in the crowd. People with big lenses and solar filters on their cameras started snapping pictures constantly. (I, unfortunately, did not have a solar filter for my camera. Next time…) We watched the partial phases through about halfway to totality. Most were watching the sky. I kept glancing at those thick, low clouds getting closer.

At about T-0:30, a band of low level, thick clouds moved in. We couldn’t see squat. Excitement had turned into despair.

Folks were not thrilled with this turn of events. We would occasionally get a second or two of enough clearing of the clouds to see how the partial phase was progressing, but they never lasted long. And the clock was ticking.

Less than thirty seconds before totality, a brilliant sliver of sunlight appeared almost directly overhead, a crescent 🌙 of light that announced the end of the partial phase.

The crescent shrank over the next 30 seconds,

Noted now – it was closer to five minutes, not thirty seconds, going from the timestamps on the photos. Time is an interesting thing in these circumstances. I would have swore it was much less time, but the data doesn’t lie.

then vanished

as the “diamond ring” effect was visible.

(Blow this up to full screen size and look at the detail I caught in the clouds and the sharp edge of the moon’s lower edge. Blind luck, no skill, but considering that a half hour earlier we were sure that we would miss totality completely, a little bit of leftover luck was welcome.)

Another one to blow up to view on a full size screen. These two pictures may be on the short list for the most favorite pictures I’ve ever taken.

The full “Diamond Ring” effect – a little blurry since A) I had the camera in “auto” mode instead of “manual” so as it got dark it went with longer and longer exposures, and B) I was holding the camera instead of having it on a tripod. In retrospect – OOPS!

Looking at the file timestamps, from the first “diamond ring” photo where you can start to distinguish the moon’s disk in the glare of 99.99% partial phase until it’s 100% totality is twelve seconds. Fourteen pictures.

Our surroundings became completely dark, the temperature had dropped 10°F or more,

Unless you’ve seen one of these eclipses in person, you truly won’t believe just how fast it gets dark and how much the temperature drops in that last minute or two.

The corona appeared in all of its glory. The crowd went berserk.

Still a handheld photo, still with the camera seeing a dark sky and waaaaay overexposing the corona. If we had gotten the entire 4:24 of totality I’m sure that I would have had the time to check the pictures I was getting, realize what was wrong, and fix it. As it was, we all knew that the clouds would move back in any time. I was just taking pictures as fast as I could because I was quite sure that I didn’t have much time. I was, unfortunately, correct.

As I said all week leading up to this second – “It was what it was.”

I had several video cameras running on their own, so with the big lens in my hands I was banging off images as fast as it would store them. I had enough time to shoot 24 pictures in 26 seconds before the clouds completely covered the fully eclipsed Sun. The one adjustment I had time to make for the last three pictures was to pull back on the zoom lens, from 300mm to 75mm. Still overexposed in auto mode, with the clouds getting thick fast.

It was freakin’ glorious. While the photos may not have turned out as well as I had hoped, looking at the fully eclipsed Sun through the telephoto lens was spectacular. There wasn’t a ton of detail visible like you’ll see in any of the truly amazing pictures where folks had a clear sky. The clouds blurred out a lot of that detail. But the corona to my sight through the telephoto lens was a bright circle, razor sharp on the inside where the Moon’s surface was and spreading out over a “Moon diameter” distance in all direction with a fuzzy outer edge. I could not see any prominences or flares, but I could clearly see that the inner edge had a pink and red tint to it.

Twenty-six seconds of totality. Then the clouds came back over for good. Our window of opportunity closed.

During the rest of totality everyone continue to party. There was screaming, hooting, hollering, singing, crying – and that was just me. Well, me and fifty thousand or so of my new best friends. In all 360º there was the “sunset/sunrise” effect, the sky an orange or golden color as it would be when the Sun was still below the horizon. Behind us the “sunrise” was coming as the Moon’s shadow raced across the Earth at about Mach 2. And “sunrise” was coming from the south. In 2017 in Nebraska we saw this effect much more prominently, mainly because there we had almost all high clouds and could clearly see the horizon all around. In Texas, the villain clouds were much lower, so the view all the way to the horizon was also blocked in several directions.

If it had been clear and we got the entire 4:24 of totality there were a number of other things I had wanted to look for. Jupiter and Venus would have been bright and easily visible, with Mars, Mercury, and Saturn also naked eye objects if you knew where to look. There’s also a comet that might have been visible to the naked eye, and definitely would have been visible in binoculars. (Which I had ready.) No joy on any of that due to the clouds.

As I said, I had multiple video cameras going, including the incredibly fashionable forehead-mounted GoPro. We’ll see what that caught. It should be fun.

We couldn’t see when totality finished, but the clocks told us it had to have happened and it started to get brighter. The total eclipse was over. We were still clouded out.

About six minutes after totality ended, the clouds thinned enough for a few seconds to catch the post-totality partial phases. We saw much less of the partial phases after totality than we had before totality, the clouds being much thicker and lower.

We hung around the festival for a couple of hours to let the crowd disperse. There was music, birds in the river (ducks, geese, a couple of different types of herons – more pictures later, of course!), vendors, and food. Finally it was time to pack up, hike the two miles back to the hotel (I really need to be in better shape, or ten years younger, before the next eclipse), and go out to dinner. I had expected total gridlock and the restaurants to be packed beyond capacity with over 200,000 extra folks in town, but they weren’t there, so traffic and dinner were fine.


What’s next? I’m thinking there might be some opportunities for travel.

From Utah to Mississippi has 5:00+ of totality, and from Mississipi to Florida you’ll see 6:00+. Holy Guacamole, Batman! I’ll only be 88 years old then, that’s TOTALLY doable! Then the path of totality continues on over the Bahamas, Haiti & the Dominican Republic, Guyana, Suriname, and the east coast of Brazil.

Keep your passport current and keep hoping for clear skies!

Eclipse Minus Twelve Hours

Look at this gorgeous sunset from San Antonio tonight!

It’s not quite “clear and a million,” but it would do for tomorrow.

Totality in Kerrville starts at 13:32 CDT. There’s mow a 77% chance of “clouds” then, but that could mean something like this (which would be FINE) to heavy, thick, low rain clouds (which would NOT be).

It will be what it will be. But if any of the gods are listening and could deign to cut us some slack, we’ll take it.

“Some days it’s better to be lucky than good!” I’ve been good – now I’ll graciously accept some good luck.

Clear skies, eclipse buckaroos!!

Eclipse Minus One Day

Our forty-hour forecast is for an 82% chance of clouds. (It was 84% two hours ago, so… yeah?) But they don’t say if that means heavy, low, thick clouds or high, thin clouds.

It will be what it will be. We had discussed alternative plans if anything “nearby” looked promising. At this point, everything from Mexico to Ohio looks lousy. So we will sit tight and hope for the best.

Today however, was a different adventure. Four hours south of San Antonio, on the coast…

Here there be rockets!!! 🚀

Boca Chica, where SpaceX Starships and Superheavy boosters launch.

They’re setting up now for their third full test flight.

The “rocket garden” with three old Starship rockets, including the booster that was the first to fly and land successfully.

We may or may not get clouded out on Monday, but this was a spectacular way to spend the day!

It’s an adventure! It’s fantastic!

Welcome April

And the sprint is on!

Okay, it started days ago, but we’re now less than seven days out from the eclipse and las than thirty-six hours from when I’m supposed to hit the road, so I guess it’s more accurate to say, “The panic is on!”

Which is not to say that a few minutes couldn’t be spared to watch tonight’s sunset launch out of Vandenberg of a SpaceX Falcon 9 rocket.

Look closely and you can see a bright dot that’s Jupiter, just to the left of the palm tree tops. This exhaust plume was drifting in the high altitude, sunset skies as I was waiting to hear the sonic boom about nine minutes after launch, a couple minutes after the second stage had disappeared over the southern horizon. That sonic boom was very noticeable – not like it was going to shatter windows, but it was a pretty good “thump.

You might be able to hear it just a few seconds before the end of this video, just before I said, “There it is!”

Eclipse Minus Twelve Days

Celestial mechanics. It truly is like clockwork.

Take a moon a quarter the size of it’s primary planet, put it out a quarter million miles, let angular momentum and four and a half billion years roll by, and it ends up right there tonight, headed for right THERE in twelve days and thirteen hours. Mix in an atmosphere, some haze and fog, diffraction, refraction, Reyleigh scattering, and you end up with a weird looking arc of bright orange peeking over the horizon.

Whip out that cell phone, hold really, REALLY still, and maybe you see this.

Wonders abound, all around us.

Sunset SpaceX Launch From Vandenberg

When a rocket launches it leaves behind it a trail of exhaust. From the rocket itself there’s a V-shaped plume of exhaust that grows bigger and wider as the rocket ascends and the air pressure drops. This can sometimes be tough to see during daylight unless you’re close to the launch site. At night it’s much easier to see the rocket and V-shaped plume since the rocket is so bright, but you often can’t see the long plume behind it because there’s nothing illuminating it.

But there’s a sweet spot, for a little while after sunset (or before sunrise, but getting up that early? who needs that sort of negativity in their lives?!) when it’s dark enough overhead to see the rocket, but the Sun’s still shining over the horizon to illuminate the plume…

I didn’t figure it would matter at all. We again had several pop-up thunderstorms that weren’t in the forecast at all (what IS up with that?) and late this afternoon we were getting light showers and we weren’t watching anything in the sky except the bottoms of some thick, black clouds.

But I checked again just before the SpaceX launch, and it was surprisingly clear. I kicked the “LIVE!” button in Facebook.

It was AMAZING!!

The plume had gone from horizon to (almost) horizon (there’s a tree there to the southeast) and the lighting and timing were perfect.

In the video you can see the first stage come up from behind the mountains (0:56), shut down and separate from the upper stage (1:42), the second stage light (1:49), the first stage falling behind with occasional white flashes from the cold nitrogen gas thrusters it uses for maneurvering (2:37 & 2:39), and the two fairing halves separating and falling away (2:46). If you listen carefully (or are using headphones) you can hear neighbors from a couple of spots through the neighborhood hooting & hollering.

Even fifteen minutes after the launch, the plume was still illuminated as the upper level winds twisted and dissapated the exahust, still lit from the Sun far over the western horizon.

Online on social media you’ll see videos and pictures from all up and down the California coast, from Pismo Beach to San Diego, down into Baja, and inland in as far as Palm Springs, Phoenix, Tucson, and Las Vegas. There’s even one picture from a guy somewhere over the Rockies at 34,000 feet, hundreds and hundreds of miles away.

It was quite the show!
