XWCL has a lot to be proud of this graduation season. Our best and brightest donned their funny hats and walked across their stages. What? You haven’t seen their defense blogs yet? Shhhh. The actual degree part, they’ll get there. Today is for celebrating!
First up was the Optical Science graduation.

We wish them the best of luck in their future work!
Congrats on the Academic pageantry, and we can’t wait to see you all defend!
Last time, on extreme.ao: We were still having weather. Your AO operator valiantly tried to lock the loop on a 10th magnitude star through patchy cirrus before our observers took pity and let us switch to something brighter. But finally TO Hernán got the call, stepped outside for some professional cloud watching, and the dome closed at around 11pm. The first shift crew trickled out, the second shift trickled in, and I got caught somewhere in between taking calibrations on our internal source. I took the bright moon walk down the hill, appreciated what I could of the night and the cold before finally heading to bed at 2am.
The patchy clouds responsible for our WFS’ variable flux. A moon bow! Just the right thickness of cloud to get a ring of scattered light from the full moon.
The take down crew (Laird, Logan and I) caught up with the returning night shifters (Jared, Joseph, Jay, and Josh) at breakfast. (Am I self-conscious about being the only violation of the first letter name crew segregation? A little.) Turns out we did reopen! Around 3am the clouds cleared enough for us to rush to the transit for Gabriele’s early morning target. Only for wind to spike and seeing go from 0.8 to 1.5as soon after. Just before sunrise, they called it, and started the decabling soon after. Gabriele, though not captured, helped out too. A champion among guest observers. You’re welcome back any time, Gabriele!
DM decabling in the wee hours of the morning.
Night crew, full of orange juice and toast (as per PI procedure), headed for bed while us day crew revved our way up to the mountain. We only realized how much we had to thank the decable crew for when we rolled up to the platform. They had made our jobs a walk in the park. Cables and electronics box already down on the dome floor, the cart ready to go, with the bumpers out of the way, MegaDesk completely dismantled int the control room. They won’t always tell you they love you, but there will be signs.
We still had plenty of work to do to get out of the telescope’s way by noon, when the next night’s instrument would be rolled into our place. Yesterday we met before dinner to go over the procedure, and this morning we expertly executed said procedure. Except a few bolts that felt especially sticky (*COUGH* legs side B outer bolt *COUGH COUGH*), the cart and lifting hardware behaved itself beautifully.
At the briefing yesterday, everyone was very briefed on the new lift position.I hold the instrument steady as the cart gets assembled. Laird and Logan reattaching the hardware that keeps pur instrument safe from earthquakes.
Juan and his crew helped us go from legs to cart, cart to elevator, elevator to 40ph wind tunnel, to the final tour town the hill. Laird was there to help oversee the careful maneuvers with our precious wheel-bound table of optics. He was also there to document just HOW MUCH WIND we’re talking about.
The wind was so strong it knocked over Laird!Baade, snow capped mountians, an AO instrument on the move.Movign the electronics rack back to the clean room.
Where were Logan and I? Frantically shuttling computer parts, cables, and all our other bits and bobs out of the telescope and down the hill. We try hard to be polite and get MagAO-X junk out of the control room ASAP. As it happens, ASAP turns out to take 3 car trips of stuff and gets us done just before lunch. And MagAO-X is back where we want it, cozy and protected from the elements in the cleanroom antechamber.
Everyone is back in the cleanroom, and room temperture.
AND POOF. We’re back! Actually after lunch I fell asleep for an exertion-induced nap, during which Laird, Juan and crew got us back on legs and back in action. The afternoon was full of unwrapping, dusting, power supply cursing musings, and positioning MagAO-X where it will live for the summer before we come back down for 24B.
MagAO-X positioned in the cleanroom to maximize 1) sharable space with other isntruments and 2) sticker visibility.
What does it take to get MagAO-X cleanroom ready? A lot of organizing, reshuffling, and repeating steps we did on the telescope platform. There were a few special quirks with the new placement in the cleanroom and making sure everything got the power it needed.

Some of the crew (Jared Jay Josh – J^3) will be staying an extra day to make sure everything is in good condition for our summer remote ops. As for the rest of us, this is our last night at LCO for the 24A runs! For the special occasion, we made sure that we took a last sunset as a team, with a special surprise for Jared.
The largest sunset group photo. See reflections for a captured Josh.
The glasses looked so good, how could we not take a few extra shots?
Best 15 minutes of the day? Finding out there was pizza for dinner, eating pizza, thinking fondly of the pizza, and getting a second serving of pizza. But of course, the pizza tastes better with the laughs shared at dinner with our AO family.
Song of the Day
Today’s song brought to you by the bitter sweet of leaving the mountain after a hard run.
Thank you for tuning in for “Eden’s screenshots of the firewalled LCO weather page.”
Bright eyed enthusiam coming to you straight from the AO operator desk.
I have good news and I have bad news. The good news is that we are open! The bad news? The seeing is just on the edge of usable. And by “on the edge” I mean we’re getting something on the science cameras… but it’s the kind of data we dread to process. What a tease.
On top of that, the wind is whistling something fierce. Like living next door to a two-note pan-piper. Every 5 minutes, Maggie-O-X will announce that we’ve hit our wind limit, just for the wind to slink back down again. Like a threat that it could shut this whole operation down, clouds or not. We thank Carla for being a merciful TO, and we are planning on allocating portions of our empanada orders tomorrow to her, accordingly.
Seeing and wind plots at the time of reporting.
Did I forget to mention that I have worse news? In a novel first for this team, we are expecting rain. Yes, in the Atacama Desert, that gets an average rainfall of 15 mm a year. We found it, folks. The one day of rain a year. Stay tuned for the MagAO-X raincoat wrappings.
The first time I have seen precipitation on the LCO meteoblue weather page.
Weather like this could really get you down, but luckily we have a great team that keeps even these kinds of days full of laughs and good stories. Our night started with high hopes. Since the sky was clear and the winds were low, the walk to the telescopes was appealing for the first time in a week. Some of the team caught a crisp green flash on their way up.
As an early-shifter, I’m headed to bed, but I know the control room is staying merry with Alycia wisdom, Jared sea stories, Joseph whimsy, and Josh punchlines that are actually just events from his life. All as it should be.

Best 15 minutes of the day? Filling out the night lunch for 4 whole empanadas. Just like the boss ordered.
Overheard at LCO
“I struggled with the scissors unit in kindergarten”
won most improved on MagAO-X scissor duty
“As long as I’m not playing a sport I won’t get injured” “Why would you say something like that”
someone who could definitely get injured in offseason
“I will be Clay’s Gollum”
someone with career ambitions
“Keep the icc data away from the tea.” “How about you keep the tea away from the icc data.”
not all of us have Sebastiaan level tea charisma
“I wasn’t allowed near the model trains because I kept wanting to touch them”
We made it!Some of us (one of us) lucked into the customs fastpast lane.The traditional Starbucks renaming: Jren – Eden, Josh – Logan, Maggie – Maggie
Guess who’s made it to Chile? Everyone else! You know it’s almost time to put the instrument on the telescope because the brawn has arrived en masse. We were luckier than last run 5/5 of the expected graduates / Postdocs made it to Santiago unharmed and on time.
Photo evidence of everyone being a good sport after 24 hours of travel.
On our way from the La Serena, we all jammed into the mini van, with just the cubic feet needed to fit all of us and our luggage. It was the hardest jenga our sleep deprived brains could probably have accomplished at that point. Fortunately it was just for the quick jump to the halfway house for astronomers, the Pine on the hill. We had to wait here for a bit before our larger, more official van shepherded us the 2 hours to the telescopes.
Yep, the lounge is still here, and the snacks are revitalizing. Taking the 2 hours at el Pino for a much needed stretch break.
Meanwhile, our compatriots up the hill were enjoying a luxurious empenada lunch, after a hard mornings work of calibration tests and computer construction. Some of us travelers were lucky enough to be visited by the masked empenada fairy, delivering the delicacy to our unoccupied rooms.
There times when a day shift overlaps with empenada days are few and they are treasured.
The travel crew arrived, some well napped, others full of podcast, to a chilly mountain top that feels a little more like home every time. After some necessary rest and recovery in our rooms, we finally joined the mountain team for a big dinner. We’ll be back to big work tomorrow, but for now we get to rest (on real beds, not half naps van or airplane seats). The clouds weren’t looking promising, but they sure did make for a pretty sunset:
These are the kinds of sunrays we expect in Tucson.The only way we could possibly make the new glass stickers more majestic.
The best 15 minutes of the day was getting to see a friendly face from the past! Casey Lam, who was once upon a time a grad student working with Jessica Lu when I was a mere undergrad, just so happened to be the observers before us on Clay. She’s now a postdoc with Carnegie in Pasadena! With the buffer day we need to get the instrument on the telescope, I got to spend a good 15+ minutes catching up before Casey observes her last night and heads back down. Have clear skies and safe travels, Casey!
I am very excited I got to see Casey!
Song of the Day
To be completely honest, you’re getting a blog post from a pretty tired kid, just maybe the least tired and least busy. See you tomorrow where we’ll be a little more alive!
First sighting of a large water body since early March.
Like any triumphant victory, the champions must eventually turn homeward. After an amazing few weeks of scientific discoveries, engineering miracles, and accidental binary friends, we packed up our many multi-terabyte hardrives and headed down all 8000 ft back down on our way home.

We had an early morning bus filled with some napping, clear skies and a view of the bay. Post drive we got a quick break at El Pino, enjoyed the sights, touched grass, and confirmed that there was still that weird vizzy people were calling a rabbit. After a brief respite of healthier snacks and preferred beverages, we all packed back in the van and left for the La Serena airport. All except for Josh, who by a cruel twist of fate was the only lab member who got completely rebooked with a separate itinerary back to Tucson. We miss him to this day.
Last known photo of Josh Liberman.
And then the whirlwind of luggage hauling, TSA searches, elite lounge scouring, airplane sitting, more TSA, and sleep-deprived airport navigation began. Despite the 36 hours in transit, we did make time for the important traditions.

But just like that, or maybe “after all that”, we finally emerged blinking in the Tucson sun. After clunky suitcases were retrieved, goodbyes were brief. It’s hard to be sentimental on dubious amounts of red-eye sleep and to people you have just spent three weeks secluded mountain top, stepping on their toes.
One of the many attractions of Chile includes some friends, the Gemini telescope.
But like any epic tale, why not tell it twice? Your favorite AO squad couldn’t resist the encore to such a successful run, and we will be back in May for 24Ab. In the meantime we will be catching up on our sleep debt, hugging our loved ones, and quickly putting in a load of laundry.
