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…

Belt Of Venus – West Texas Style

Last night I shared a picture looking west at sunset from a rest stop off of I-10 in west Texas, just east of where I-10 and I-20 split. But if you look the other way…

I’ve mentioned and shown pictures before of the “Belt of Venus,” an astronomical phenomenon seen in the eastern sky at sunset.

It’s simply the Earth’s shadow rising in the sky as the Sun sinks below the opposite horizon.

It can be clearly seen, even from a city like Los Angeles, but it was spectacular from a dark location in the middle of nowhere in a “clear & a gazillion” sky.

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!

The Dark Side Of The Moon – Literally

What a roller coaster ride!

When I got up this morning it was mostly cloudy, with low clouds and fog, but the Sun occasionally popping out for a second or two.

We stuck with our plan and stayed in Kerrville, going down to the local park where there was a huge eclipse program planned, open for free to the public. The skies continued to improve.

Up until about thirty minutes before totality, well over halfway through the partial phases, it was plenty clear enough to see the Sun.

Excitement levels were high. We got a talk by NASA astronaut Reid Wiseman, who is the commander of the Artemis II mission to the Moon.

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

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, then vanished as the “diamond ring” effect was visible. Our surroundings became completely dark, the temperature had dropped 10°F or more,

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

It was spectacular!

We had 4:32 of totality, but the fortuitous hole in the clouds closed up tight. We saw nothing more of totality. Our surroundings stayed dark, the frogs started croaking, the ducks flew back home, and we could watch “sunrise” rush at us at Mach Two from the south.

After totality ended, it continued to be cloudy and cool. We stayed and enjoyed the festival for another couple of hours before walking the two miles back to my hotel.

We needed a break and got it.

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 Seven Days

Doomscrolling through the weather sites…

Too many of the predictions are pointing toward something that looks a lot like our front yard in SoCal this evening. For example,

(Plot by Tomer Burg, arctic.som.ou.edu)

This is the “GEFS Downward Shortwave Radiation” prediction. I won’t pretend to really understand what all of that means, except grey means bad and blue means good, and where I’m headed is the second darkest shade of grey. And there are dozens and dozens of different models, different agencies, different colors, different data sets – they’re all pointing the same way.

This prediction was generated ten days out from the event, so it’s going to change, possibly by a significant amount, but likely not by a ton. The details will get more refined for all of those exact locations, but in broad strokes, it’s looking a lot like there are going to be significant clouds along 90% of the eclipse path, all the way from Mexico to the Great Lakes.

We knew this was a possibility. I am very surprised to see so much of the eclipse path covered in clouds. Normally I would expect a couple of storms possible, which means maybe driving toward the Mexican border or up toward Arkansas. But needing to drive all the way to eastern Ohio???!!!

It will be what it will be. You’ll hear me saying that a lot in the next ten days. Barring some disaster I’ll be in Texas next Friday, spend the weekend there watching the forecast and going over options, then taking our best shot on Monday. I have no control over the weather.

Say goodbye to March, friends! It could have been worse, but it sure could have been better as well. Let’s hope that April finally cuts us some slack, especially with the cloud cover on the afternoon of April 8th!

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.

Eclipse Minus 24 Days

Simple messages:

1) Be careful to watch the partial phases of the eclipse carefully and protect your eyes!
2) If you don’t already have safe eclipse glasses and you’re going to watch the eclipse, get them now! They’ll sell out quickly.

Never look at the Sun without protection except for when it’s 100% fully eclipsed. For those 4:24 you’re going to see one of the most amazing sights in the entire Universe and you can whip those glasses off and see it in all of its naked eye glory. But for the partial phases for a couple hours before totality and for a couple of hours after totality, you MUST have protection for your eyes.

And NEVER look at the uneclipsed Sun with binoculars or any kind of magnification without special solar filters designed specifically for that instrument. You can cause permanent vision damage or loss in just seconds.

When shopping for eclipse glasses, make sure you only buy from reputable sources and manufacturers. There are reports already of many sellers on Amazon and elsewhere that are are pushing knock off glasses that don’t meet the proper standards for protecting your vision. I got mine from 2024eclipse.org. (For a package of ten I paid $27, including tax and shipping, so that should give you a good baseline for how much you should be paying.)

At the end of the day, if you can’t get certified eclipse glasses and April 8th comes and you still need a way to look at the partial phases of the eclipse, there are other options that don’t involve looking directly at the Sun. We’ll get to those another time.

Order now, be safe!

The Race Is On!

It’s going to be a marathon and an adventure. It might be stressful at times but I intend to make it glorious, not exhausting.

It’s a four-dimensional finish line to this race – space and time. The space – Kerrville, TX. The time, 13:32:07 on April 8th, 2024.

(Image: NASA Scientific Visualization Studio)

Kerrville is expecting somewhere between 300,000 and 500,000 visitors for the day of the eclipse. It’s going to be a madhouse.

To get a room there a four-day minimum was required, non-refundable, and at somewhere between three and five times the normal hotel rates. Ye olde “supply & demand” at work!

I’ll be driving out from Los Angeles, about twenty hours of driving, but over three days. That should give me sufficient slack to allow for any unexpected issues or detours.

I didn’t even think about flying out and getting a rental car – those reservations were pretty much booked and overbooked months ago.

In order to take that time off of work I’m going like a banshee now to try to not only keep up with my current workload but to get ahead and stay ahead for when I leave. (No good deed…)

So, a marathon, to have my butt and hopefully a trunk full of camera gear in a sunny spot in central Texas in the early afternoon twenty-seven days from now.

It WILL be glorious!

Clear & A Gazillion

See that Sun? We’re only one day away from the new moon, so somewhere in this view is also that Moon, even if you can’t see it. (It’s probably about where the tops of those palm trees are, about 15º-ish west of the sun.)

You can’t see the Moon because it’s being seriously backlit by a freakin’ bright star, but it’s still there, creeping in its orbit closer and closer to an alignment which is perfect… But this month, they’ll miss. No part of the Sun will be blocked by the Moon from our viewpoint, and conversely, no part of the Moon’s shadow will touch the Earth.

Next month, on the other hand…

In 28 days, on April 8th, the alignment will be absolutely perfect and the shadow of the moon will swing in an arc from the Pacific Ocean toward the northeast across Texas, Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine, before heading out over the Canadian maritime provinces.

A map of the contiguous U.S. shows the path of the 2024 total solar eclipse stretching on a narrow band from Texas to Maine. (Map from NASA’s Scientific Visualization Studio)

Yes, I’ll be there. With my son living in San Antonio, I’ll be headed to Kerrville, TX as my base, sitting right on the centerline of the path of totality with 4:24 of totality.

Yes, you’ll be hearing about it here. Probably just about every day once we get into April.

If anyone has questions, feel free to drop them into the comments. I’ll try to answer them all.

Clear skies!!!
