MagAO-X 2022B Day 5: ¡Ya basta!

The truckers are politely “only” causing traffic jams rather than a full blockade, but if you depend on freight vehicles for your business—or telescope operations—you’re still hamstrung by the fact that a ton of the trucks in Chile are busy blocking roadways and not shipping goods.

The government has read them the riot act and started detaining people. Negotiations continued today with some initial promising statements from the truckers. They continued until quite a late hour this Saturday only to remain stuck on the trucker union’s demand for government price controls on fuel. So it sounds like Sunday will remain truckless, and instrumentless.

On the plus side, we do not have thousands of tons of fruit in danger of rotting, or salmon that needs to be shipped immediately. We just sit in our rooms, screwing around doing important science stuff on laptops, and popping over to the lodge for our three square meals a day. It’d be quite relaxing, if it weren’t for the looming threat of losing telescope time worth roughly $50k a night—and the super intense compressed schedule to get on sky ASAP when the instrument gets here.

I don’t believe I used a blog post to announce our official patch design for 2022B, but now’s as good a time as any.

This is Gabriela the gata Andina (Andean mountain cat). The patch vendor did a great job simplifying my artwork, as always, but gave the cat a bit of a suspicious look.

In light of current events, I would like to present my online-exclusive patch design:

Gabriela dice: “¡Ya basta!”

The sunsets here on the mountain are incredible. Arizona can do some great stuff with monsoon clouds, but there’s this difficult-to-capture lilac band across the cloudless sky at sunset here that is beyond compare.

Some people only have eyes for one thing, though.

Also, I met a cool lizard but I didn’t catch their name. Anyone know them?

Aside from that, not much to report. Eden, Avalon, and Jialin arrive tomorrow, so we’ll have some more bloggers. (And, when the instrument shows up, hands. But who can say when that will be?)

Song of the Day

The connection to yesterday’s Delirium by The Dead South is… Saskatchewan!

Yep, more Canadians cosplaying my Southern roots. I like the song, though.

MagAO-X 2022B Day 0: Launched to LCO

Well, @warrenbfoster still owes us vacation photos from Valparaiso, but who knows what his internet situation is. Someone’s still gotta write the Day 0 blog post, though.

Hello again, LSC hardstand.

Compared to last time this trip didn’t have many surprises. We did learn several things, though:

  • When there’s a choice of LATAM and Delta for the 10-hour flight, Delta’s got the better seats. Jared reports leg-room upgrades on LATAM are barely anything, and not worth the additional cost. I had to sit on my complimentary blanket to sleep because the hard seats were tough on one’s rear after a few hours.
  • COVID-related arrival measures are entirely gone. No test on entry, no verification of vaccine documents. The Ministerio de Salud has dispensed with mask-wearing requirements indoors (except for healthcare settings) and most employees and passengers opted to go bare-faced.
  • Passport control took a while, but kept moving. Single line for nationals and foreigners.
  • Customs enforcement seems to be up. The scannable tags system that was new last time is now gone, replaced with brief interviews with Jared and myself about equipment we were carrying. We aren’t importing anything (of course) so we explained we had tools for scientific research and they let us go.
  • They no longer seem to care about the purpose or destination of visits. I have a slip saying I’m visiting Santiago for vacation that I must present on exiting the country, but I was never asked for those details.
  • As always, the “collect your bag, complete customs, re-check your bag” dance is a pain. Unhappily we must report that LATAM domestic baggage recheck is now even sillier. There is a counter in the international terminal, down the hall with the taxi stands right after customs but before you actually exit. It was super backed up and after waiting 10 minutes not one person had successfully re-checked their bag and left. If it’s not busy, it might be better than the situation across the road. We schlepped our bags across the way to the old terminal (T1) and went to a place with approximately 4 actual agents and all self-service kiosks. Of course, the self-service bag check does not work with our pre-tagged bags so you can go straight to the “I need an actual human” line.

“Preparada” by El Columpio Asesino

Okay, so the song’s about a violent break-up but… we are preparada for 2022B.

Someone should probably come up with Song of the Day rules.

MagAO-X Voyage à Montréal Day 1: My French isn’t that good

The SPIE Astronomical Telescopes + Instrumentation conference is the main event for instrument builders world-wide, and this year is held in Montréal, Quebec, Canada. The conference is held every two years (because one year is nothing in instrument project timelines) and the last one would have been in 2020. (But then, the plague.)

Anyway, we have a lot of new stuff to report from MagAO-X, and from our friends in UASAL, SCExAO, and beyond. See the schedule at the end of this post. (We’re just jazzed to be here.)


Today, the first team member to speak was our fearless leader with a status update on MagAO-X Phase II and future plans.

Olivier Guyon gave us a version of his Spirit of Lyot talk, which was fortunate, because that gave some of us a second chance to absorb and understand it. (There’s a lot going on over at SCExAO!)

Sebastiaan was tapped to present as a substitute for a team member who wasn’t attending, and he gave us an overview of image quality calibration from WFS PSF deconvolution (work by Jacob Trzaska) and his own predictive control algorithm (Data-Driven Subspace Predictive Control—DDSPC).

Blog Rules

It’s been a while since we had a Blog Rule, beyond the compulsory Song of the Day. So, here’s my rule for the week: les chansons doivent être en français.

(The songs must be in French.)

Bonus points for chansons Quebecois!

“Je Veux” by Zaz

Today when I went to get a coffee en route to conference registration, I opened with a “bonjour,” following the advice for anglophones in a francophone world. Then, I asked “English OK?” and the barista said “Yeah, sure! My French isn’t that good.”

Maybe that advice is more for the rest of Quebec…

MagAO-X Across The Pond Day 4: Let’s Talk It Out

Today I presented Kevin Wagner’s talk about searching for planets in 10 µm light. I think I did an okay job talking about things I know nothing about, but then, I do have plenty of practice.

All questions about Kevin’s part of the talk will be answered with viscacha noises.

Incredibly, people did ask me questions. In this rare instance, “beats me, ask someone else!” was a valid answer. (Actually, I’ve been running audience messages back and forth to Kevin on the Steward grad student Slack. Just not on stage.)

The only MagAO-X/XWCL member officially on the schedule for today was our fearless leader Dr. Jared Males.

GMagAO-* is strictly an improvement over MagAO-X as the * means it can wildcard match all Giant Magellan AO instruments.

I can’t speak for Jared, but I’m happy to be free of any further obligations beyond listening and enjoying the rest of the conference.

MagAO-X 2022A Day 29: Non-Working Title

We did it, folks. We made it the full 29 days. (Maybe there will be a blog post from Atlanta for Day 30, maybe not. Depends how tired we are.) Jared had the presence of mind to take a group shot on our transport down from Las Campanas to the airport.

The covid clinic we visted along the way (fortunately not pictured) was demystified by Justin’s blog post. The most difficult part was waiting for them to fix their printer issues.

At the airport, we saw an interesting macaroni-penguin-liveried plane. And we ordered the traditional papas fritas and Kunstmann Torobayo (on tap no less).

Then we left Laird in La Serena.

(Not really; he was on the next flight out.)

Once in Santiago’s airport we traveled, Lairdless, in search of food and drink. We ended up at notable South American eatery “Ruby Tuesday,” where we finally got Logan a pisco sour. (Due to Las Campanas Observatory’s status as a dry site, there wasn’t a chance previously.)

I dunno, this stuff could catch on. Maybe they’ll expand their franchise to the US!

We’re all about ready to collapse into our assigned seats now.

However, the blog must go on, so I leave you with your…
