MagAO-X 2026A Day 22: Look’d up in perfect silence at the stars

There is an eerie silence in the Clay control room. It’s a bit like a spooky Twilight Zone episode where everyone has disappeared, but their disembodied voices periodically ring out.

Left: Clay control room on December 6, 2025 with a sizable part of the MagAO-X team. Right: Clay control room on May 2, 2026 with, well, just me.

Despite the remoteness of 2026A, it made sense for me to be here, as I will be spending the rest of the week at LCO meeting with colleagues to work on a new Magellan instrument called MagNIFIES. When it comes to Magellan in about 4 years, it will be the best infrared spectrograph in the world. How awesome to use one amazing instrument and plan another in the same week.

I arrived yesterday, hung out a bit with the MagAO-X remoters and visited Baade by moonlight to see the engineering in action (their control room was almost as crowded as when the MagAO-X team is here).

Baade pointed south during engineering and lit by the Moon.

Speaking of the Moon, my flight was landing in Santiago just as the Moon was rising. The couple in the seats in front of me asked the flight attendant why it was such a strange color. The flight attendant turned out to be a keen observer of the sky from the plane, and clearly understood that the Moon could only be seen like that at certain times of month and that the orange was normal (but she didn’t mention Rayleigh scattering). In contrast, a few minutes later, the people behind me, apparently less keen observers of the sky, asked her, “What is that thing?” and had trouble believing it was the Moon.

Carla captured this photo, a night later than my flight, with similar color to that which baffled my fellow passengers.

A different color is definitely on my mind today, as it is May 1, i.e. “College Decision Day,” and that means that my youngest offspring decided whither he will fly from our nest. I helped my mom find yarn in “CWRU Blue” so she could make him an appropriate hat. Yes, there is a web app for finding yarn to match a given hex code.

CWRU = Case Western Reserve University

However, unless it is allowed to be totally self-referential, that is not really a color associated with this blog post, so …

MagAO-X 2025B Day 15: An AO Puzzle

We’re all here to figure out puzzles like “Do rocky exoplanets have the same composition as Earth?”, “Do all protoplanets produce Halpha emission as they accrete?”, and “Can our AO system reach the contrast necessary to image low mass planets in reflected light?”

It turns out, we also have a lot of puzzles to solve that we didn’t realize we needed PhDs for, such as, “Why is the attempt to upgrade the AO computer cursed?” and “Why does Joseph no longer think computers are deterministic?”

Then there are the questions that make us think we should have gone into philosophy rather than science, such as, “Why do we find clouds so pretty even though we hate them?”

Sunset yesterday

The hardest questions are the deep mathematical ones like, “Why is the seeing when I’m on the telescope always worse than the median?”

Worse than median seeing

And then there are the idle puzzles one wonders about at 2 AM such as, “What is the collective noun for a bunch of graduate students? [my vote is for ‘pile’ as in the P in PhD]”, and “How many snacks does it take to satisfy said pile?”

Perhaps a better question is, “Can we get Trader Joe’s to sponsor MagAO-X?”

I’m optimistic that all of these questions will be answered in my lifetime.

But when the seeing gets bad or the sky clouds over, the puzzles we really like are the NYT crossword type (see 2024Ab Day 10). I’ve never made a crossword puzzle before. Tonight I experimented with two free grid-creation applications, and my main takeaway is that the folks edited by Will Schortz are quite impressive. Nevertheless, here for your enjoyment is the AO Puzzle:

Fact of the Day: A record 889 contestants participated in the 2025 American Crossword Puzzle tournament, which is held every year in Connecticut.

I finally got a walkup song!

MagAO-X 2024B Day 13: These are the nights to hold on to

I think I’ve had observing time at LCO in every month (though I’m unable to figure out from the records I have on my laptop if I’ve actually physically been at LCO in every month), but this is the best November that I remember. The days are warm and lovely, the nights are clear and crisp with good seeing. “These are the days to hold on to” and “this is the time to remember.” I’m busy using this run to forget the 2024Ab weather.

Yes, that is seeing on the DIMM below 0.4 arcseconds
This is the time to remember ‘Cause it will not last forever

Even though I never forget how beautiful it here, I can’t help taking more photos of lovely sunsets and Venus next to the dome.

Oh LCO, [you’re giving] me the best of you

A lot of Magellan observations are done remotely now, but I continue to think people ought to come and experience the Observatory and learn the instruments in person. There are no shortage of students on this run, of course, given that MagAO-X is so hands-on. And I admit that I am remotely observing on two separate nights in the next month alone. But I hope some others see these photos and want to come. I fear a future when we’re all just looking at screens of telescopes.

Our Telescope Operator, Roger, doesn’t have to walk into the dome to look at the telescope. “time is gonna change”

On a different subject, I have to say that for something not very funny to 9 people sharing one bathroom in the dome, our clogged baño caused a lot of hilarity. Thanks to the heroic efforts (though I will spare you the photo) of Roger, Laird, and Parker, the situation was resolved. Now we “look back and have to laugh. We lived through a lifetime and the aftermath.”

Thanks to everyone (including the missing Jared) for their help in making this a great MagAO-X run. “You’ve given me the best of you”

Song of the Day: Anyone my age knows the song I’ve been quoting as it was absolutely unavoidable in 1986-87 and possibly the prom theme for every senior class in America in 1987. Magellan wasn’t my first love, but “I’m warm from the memory of days to come.”

MagAO-X 2024Ab Day 10: “30+ years of speckle”

This week could have gone better: Delayed and missed flights, fog, clouds, bad seeing, and I got a head cold. New at LCO this trip: no Covid test on arrival. In case you’re wondering, I brought my own, and I don’t have Covid.

Last night, I turned the super fancy MagAO-X system with its three deformable mirrors into a very expensive speckle camera. 30 years ago, when AO was in its infancy, I did my PhD thesis taking short exposures to “freeze” the seeing and a lot of Fourier transforms to recover high spatial resolution images. Well, in 1.3″ seeing, MagAO-X could still do some correction (miraculously) and the EM-CCDs in MagAO-X can run fast (I ran at about 60 ms, which is considerably longer than the normal coherence time at visible wavelengths). I can play some of those old speckle imaging tricks on images like this:

60 ms image of a binary star
First try at an average image (zoomed)

See the binary star? Of course you do. I select the best of the tens of thousands of images I took and average them up. Combined with other data I have, these images will let us measure masses of the stars.

Tonight, however, the seeing is finally down to median LCO conditions and the forecasted clouds have not yet arrives, so MagAO-X is weeping tears of joy:

A saturated PSF with all those Airy rings!

I may be bummed about the weather, but it’s been fun to be back here and collaborating with the ever-growing team. People are working shifts, so we didn’t get a photo of everyone, but here’s an obligatory sunset selfie with clear skies above.

May 19 sunset selfie thanks to Logan.
MagAO-X womens’ team tonight.

And, dear reader, as a devoted blog follower you undoubtedly know that as predictably as the approach of winter brings clouds, Sunday brings:

Empanadas, of course.

I saw a fox today too, but sorry, I didn’t get a picture.

Today’s best 15 minutes were spent finishing the Sunday NYTimes Crossword Puzzle with the band of Js (Joseph, Jay, and Josh) as we froze speckles.

Pride in our accomplishment

Song of the Day

I almost went with Lady Sings the Blues, one of my favorites for bad observing weather combined with colds, but I don’t want to be a downer. So, I’m going with Freeze Tag by Suzanne Vega in honor of those fast images we took and the coming week’s temperature forecast.

The sun is fading fast
Upon the slides into the past

MagAO-X 2023A Day 16: Too Tired to Blog but This is for Katie

We don’t want anyone reading at home (Katie) to think we’re slackers here. OK, actually, I’ve never actually found Slack useful except here. Basically, MagAO-X has just precipitated my mid-life crisis. First, having joined the observing remotely in 2022A, and maybe it was the effect of all these young people, I decided I wasn’t too old to learn a new programming language. Sure, I thought, I’ll just write a whole new pipeline for a new type of data in a new language (Python). After years of telling everyone that the best programming language is the one you already know, I’ll prove that I’m actually a hip, young programmer. I tell my husband that he should be happy this is the form my midlife crisis took. I didn’t go out an buy the Ford Mustang of my dreams (red, convertible). No, I wrote Python. I didn’t quit my job as an astronomer to vagabond across the world. No, I wrote Python. And yes, starting with being here in person last Fall, I also joined the MagAO-X Slack channels. Because that’s what hip young astronomers do, right?

What would my post be without a tarantula photo of the day? It’s ok team, you don’t have to look away, I won’t post it. I don’t want to precipitate a different type of crisis (arachna-crisis?). Instead, I’ll post Jared’s sunset selfie that I got from Slack (see, I can use it!).

Alright, song of the day. It has to be Forever Young, because that’s what Python and Slack are evidently doing for me. Alphaville’s album came out in 1984, but I associate the song with my freshman year of college in 1987, because my roommate had the album on tape and played it a lot (for those not alive in the 1980s and therefore not yet ready for a mid-life crisis, tapes are a magnetic medium used to store information, in this case analog music). Somehow the song became an anthem of sorts for my then boyfriend, now husband of nearly 25 years, and me. The song is pretty emblematic of 80s youth: fear of nuclear war and suspicion of one’s elders. Each generation has its own angst.

Sometime in college, I bought him his own copy of the album on tape. At some point, I got the CD (for those not alive in the 1990s, CDs were a medium used to store digital information). Some years later when a my grad school office-mate figured out how to rip CDs, I used the IR astronomy group’s Sun Sparcstation and our CD writer (this was hot stuff back then!) to make “mix tape” CD of songs for the then still boyfriend, including, of course, Forever Young. When we finally got married, we asked the band to learn it for our wedding reception. There are some lyrics we have had wrong for so many years that we just keep singing along with ours even though we’ve looked up the words (I can’t hear them sing “perish like a fading horse” and I think “perish like a sea house” makes as much sense and fits the meter and rhyme scheme better).

Uh oh, video blocked here. But maybe those in the US can see it.
