Odds & Sods, April 14th

It was cloudy and foggy last night again and I didn’t get to see Spacex’s Transporter 7 launch out of Vandenberg just before midnight, because the weather sucked for them as well and they scrubbed. The weather is looking much better tonight, both here and there, so in twenty or so minutes (23:48 PDT) maybe we’ll get to see a launch.


SpaceX also got it’s launch license from the FAA today, the last step they needed before launching SuperHeavy Booster 7 carrying Starship Ship 24. They’ll probably try sometime after 07:00 AM CDT on Monday morning.

My son in Texas immediately asked if I would be getting there Saturday or Sunday. It’s with truly great sorrow that I had to acknowledge that I wouldn’t be making a last-minute, surprise trip. As I noted, being an adult sucks. “…For I have promises to keep, And miles to go before I sleep, And miles to go before I sleep.”


I randomly had two movies on cable on as background while I was working the other night, and didn’t think anything of it, but it hit me later how they both examine similar themes from radically different viewpoints. Things like what it takes to make us human and how we treat other sentient beings and what rights those beings might have. First it was “Ex Machina,” which has always been stunning visually as well as thought provoking. The second was “The Truman Show,” a philosophical horror show masquerading as a Jim Carrey comedy.

Are Eva and Truman all that different at their cores?


Time to try and go see a rocket launch!

Leaving The Planet

If you’re up in a few hours, there’s scheduled to be a huge launch out of French Guiana at 04:45 AM PDT, about five hours from now.

Tomorrow night, about this time (23:25 PDT), there’s a launch out of Vandenberg. (Weather permitting.) Right now we have fairly heavy overcast and fog moving in, so if it’s like that tomorrow we won’t see a thing from here. But maybe, if it clears a bit…

Sometime next week, maybe as early as Monday, maybe not, assuming the FAA issues a launch license, there’s a launch out of Texas. It will be the first launch of a full SpaceX Starship. They won’t try to go for a full orbit and they won’t try to recover either the booster or the Starship vehicle – both will splashdown in the ocean and be destroyed, the booster off of Texas and the Starship off of Hawaii after about 3/4 of an orbit.

About the same time next week, there’s a Falcon Heavy taking off from Florida with a satellite heading for geosynchronous orbit. Because of the launch parameters, all three of the cores will be expended. None will be brought back for landing and re-use.

On top of all of that, SpaceX is launching a Falcon 9 from either Florida or California better than twice a week.

And that doesn’t count any of the crewed flights, missions to the ISS, private and government. Or the Chinese space station. Or the upcoming trips to the Moon.

If you want to be leaving the planet in your rear view mirror, it’s a good time for it.

Venus & Jupiter Conjunction (Plus Five Days)

A few clouds moving in from the next storm make a great, colorful sunset.

But if you get enough light for the wonderful colors and spectacular gradient from pink to black, then you can only see Venus, not Jupiter. It’s fading. (I know how it feels…)

But if you let it get dark enough to see Jupiter, the clouds have started to roll in and all of the color is shot. There’s a life lesson in there somewhere.

Take what you can get, enjoy the moment, and watch the pretty planets.

Venus & Jupiter & Satellites

I thought these pictures were interesting, if far from perfect. They’re from the February 26th batch of pictures, three days before the Jupter & Venus conjunction.

They run from three seconds to eight seconds and they were shot with a 300mm zoom lens and the wind was blowing like a demon, so you can see that they’re a bit jittery and smeared as the camera bounced around.

That’s not why I want to share them with you.

Blow each of them up to full sized (click on the image) and you’ll see a number of very faint but visible criss-crossed lines. Better yet, save them or load all five photos in and the flip through them to animate them a bit.

You’ll see at least five items crossing the field, the faint lines getting longer as the exposures get longer.

These are satelittes, and given their close proximity to each I suspect they might be part of a Starlink swarm.

The only orbiting objects I normally capture is the ISS, which is brighter than Venus or Jupiter here. Yet at random, here I’ve spotted at least five background objects over the course of a thirty-seven second series of pictures.

When you see news articles about the Hubble Space Telescope or ground-based telescopes having trouble with all of the satellites up there ruining their observations, believe them!

Watch The Skies The Next Few Days!

If you’re just about anywhere for the next couple of weeks and you have a clear sky at sunset, look to the west just after sunset.

Remember when Venus and Saturn (and sometimes the young Moon) were all near each other in the evening sky about a month ago? Well, something similar and very bright is happening again.

This time it’s Jupiter and Venus. And for the next couple of days, the young Moon as well. For the next nine or ten days you’ll see Venus nearest the horizon with Jupiter above it, both quite bright. On March 1st they’ll appear the closest to each other (from our viewpoint, of course – in reality they’re a billion-plus miles apart) and then Jupiter will continue to sink toward the sunset and Venus will continue to rise above until Jupiter disappears in the glare in mid-March.

Again, as always for this sort of thing, ignore the mass media clickbait that will try to tell you, “TONIGHT!!!” March 1st they’ll appear the closest, but if it’s clear you’ll be able to easily see them for another month.

Yes, there will be pictures here. Later. After we get past…well…

In Los Angeles (and most of California) there’s no seeing anything other than clouds for several days as a large, unusual, and COLD storm moves in. It might not be the same cold that they’re getting in Chicago and Vermont, but there’s a finite chance that it could mean the oddest of odd events in places like San Francisco and Los Angeles – SNOW.

“1-4 inches” possible down to 1,000 feet??!! And yes, folks are asking specific questions about places near us like the Santa Monica Mountains, Santa Clarita, the Antelope Valley, and so on.

Our house? We’re at about 1,060 feet according to the GPS fix on ForeFlight.

This could be interesting…

Double Rings Around The Moon

I’ve seen & shared photos of a 22º ring or halo around the moon, but I don’t think I’ve ever seen a double ring.

The outer ring is the 22º ring, and I can’t find any reference at all anywhere to a double ring around the moon, so this might just be an artifact of some kind.

The moon is almost full (95% illuminated) and was nearly overhead, if that has anything to do with it.

Now I’m curious. Does it look like an actual inner ring to anyone else? Or is it just a circular area of glare from the bright moon off of the clouds, where the ring is like a rainbow, with the moonlight being refracted off of ice crystals to give the 22º arc?

I guess I should have taken that upper division physics class on optics!

Comet C/2022 E3 (ZTF) – FOUND!

It’s really late, I’m really short on time, but the short version is that being stubborn paid off tonight. The maps and information from TheSkyLive.com helped a ton.

Shooting blind, bracketing the framing, I finally identified that I was aiming too high on the first two sets of photos, so I went back out for a third. Do you see the fuzzy, faint, green dot? That’s the comet.

Here’s a portion of the map from TheSkyLive.com that matches what you’re seeing.

If I shoot short pictures (5 seconds) I don’t get as much washed out sky from the light pollution. But the comet is really faint and diffuse.

If I shoot longer pictures (13 seconds) I get a ton of light pollution washing everything out – but you can almost sort of start to see some of the tail. Maybe.

Here’s the frame from TheSkyLive.com that matches those two photos.

The other problem, as seen from this final frame from TheSkyLive.com, is that we’re close to the horizon, so even if the sky were clear of haze (it’s not) and/or light pollution (it’s really, REALLY not!) we would still be looking through a lot of air. So, three strikes.

But I FOUND IT ANYWAY!

Comet C/2002 E3 (ZTF)

You might have heard about the “green” comet. It’s been lurking around in the Corona Borealis constellation for a while and is now moving over between the Big Dipper and Little Dipper, headed toward Casseopeia. All of those are fairly bright constellations near the north celestial pole, so in theory the comet should be easy-ish to find.

It’s just now growing to be bright enough to be visible to the naked eye – if you’re in a dark location with no light pollution and a cloud-free, haze-free sky. “If” carries a lot of weight in that sentence. The Los Angeles suburbs and the infamous San Fernando Valley have none of those things.

Which is why I’m using binoculars, which in theory at this point should make the comet easily visible – if I’m looking in the right place.

So I’m using a map – this one from TheSkyLive.com is really good. Just make sure you have it set for the correct time and location.

For the past four nights I’ve looked, but haven’t seen it yet. On the other hand, to our north it’s been hazy as all get out, some times tough to even seen the bright stars of The Big Dipper, even with binoculars. With a faint, diffuse comet being that much harder to see, I’m not surprised.

But tonight is much more clear, so I’m going to go back out. We’ll see what we’ll see.

Comet ZTF will be getting more bright and rising higher in the sky for Northern Hemisphere viewers over the next several weeks. If you’re up late, like near midnight, or at least after 22:00, go take a look!

Saturn & Venus & Moon

One more night. The moon’s passing Venus and Saturn by and the two planets are also splitting. They’re pretty, but they’re not spectacular, while Saturn’s fading fast. (“Fast” = over the next couple of weeks, but still a lot dimmer than it was even a week or two ago.)

Not so much color in tonight’s sunset, but at least the wind’s gone. Mid-sunset you can barely see Saturn.

The moon is now three days old, something like 16% illuminated. Saturn is now well below Venus, much different than just two days ago. You can only wonder what the ancients thought of that, the “stars” moving around in what HAD to be a permanently fixed heaven.

Close up with a longer exposure you can still see the color difference. But Saturn’s apparent color will fade as it gets dimmer, mainly because it will only be visible against a much brighter sunset sky.

As always, the moon’s crescent is so much brighter than it seems when shooting photos. There’s a little bit of detail to be seen there.

But overexpose the illuminated crescent and the Earthshine-lit face of the moon is clearly visible.

Pulling out the iPhone for the wide angle picture, Saturn fades away completely, but now we’ve got Jupiter visible at the top.

Tonight I also had one of the local barred owls in a tree right above me, hooting like a fool, right up until I switched the iPhone to video. Then, dead silence. My video is several minutes long and it didn’t make a peep. I do wonder if turning on the camera turned on some sort of infrared illuminated focusing mechanism and that flashing IR signal was visible to the owl.

I wonder how much of this scene, moon and planets, can be seen by the owl. And what it thinks of it, if anything.

Maybe that’s just us.

Maybe not!

Venus & Saturn & Sunset

Tonight was the closest approach of Venus & Saturn in this conjunction. It happened about three and a half hours before these photos, but I wasn’t able to see until after sunset. That’s life on a small, round ball of dirt and water in the midst of an extremely vast cosmos.

Speaking of sunset…

Boy, howdy! Normally the most spectacular ones I’ve seen have a lot of big clouds, but tonight was a lot of very high haze. Wowsers!

I wish this photo could event begin to show all of the layers upon layers of different shades of orange and pink and peach colors that could be seen.

While spectacular, it was also enough clouds to be obscuring what I wanted to observe, i.e., Venus and Saturn. By this time I should have easily been able to see Venus, as bright as it is. But, no joy. I wasn’t at all convinced that I would be able to see Saturn when it got a bit more dark. But I went out anyway a half hour later to see what could be seen.

Stupid moi! I had sort of forgotten about that whole “moon” thing that’s two days past new moon and just the tiniest of slivers hanging there just barely above the horizon.

The other factor which I hadn’t taken into consideration was the wind. It is freakin’ howling out there, as you can see from the palm trees. I’m glad that I shot a lot of pictures, since most of them are blurred as all get out, even with the use of my heavy, “good” tripod.

It was great to see the moon slipping below the Calabasas hills, at one point with the lit crescent part below the ridge but still with part of the Earthshine-illuminated upper arc still visible. I would share that with you but all of those pictures look like I was taking them from a trampoline mounted on a roller coaster, so you’ll have to trust me on this one and use your imagination.

As it finally got dark I could see Saturn, but it was definately dimmer than last night, caused by the thin, high cloud layer. But you can see how Saturn has moved relative to Venus, past it to the right and down toward the horizon. (Of course, remember that it’s your relative view that’s changing, we’re all seperated by almost a billion miles and they only look “near” each other since we happen to be at a particular spot in our relative orbits as we all circle the sun.)

Darkness finally, cold (into the upper 40’s, which is cold for SoCal), and the gales blowing, it was easier to see Saturn.

Remember, if you didn’t get a chance to see this tonight or last night, if you get a clear Western sky about an hour after sunset, go look anytime over the next week to ten days. The two will be separating with Venus going ↖ away from the sun and Saturn going ↘ toward the sun and getting dimmer and lost in the glare of the evening twilight. But you’ve got a few days if you’ve missed it so far. Binoculars will help, if you’ve got them.

And don’t forget Jupiter overhead, or Mars back behind you near Orion.

Get outside! Take a look!
