MagAO 2018A Day 0: Cool Clio Code

Well I’m here. My trip ended up being 27 hours and it was great to get here and sleep and wake up to a delicious telescope breakfast:

Strong tea, dos juevos fritos, oatmeal, fresh squeezed strawberry juice, and 2 major astronomical telescopes closed up to sleep for the day.

I found this fine literature in the desk drawer in my room, left from a previous inhabitant:

Literature in my room (not left by me).

Today we worked hard on cooling and code. Clio code, AO code, DigiPort code. The mountain internet was down for about 4 hours. Laird arrived safely and the mystery guest got stranded in Santiago and will be here hopefully tomorrow.

I did manage to get Clio down to almost 77 K in one day! Clio drank his liquid nitrogen very well today.

The blue line is the outer dewar that I started filling first, at 10am. The red line is the inner dewar, that I started filling after lunch, when the outer dewar got below 150 K.
[Image description: A line plot with a red and a blue curve, showing the temperature dropping. The x axis is time in minutes and the y axis is temperature in Kelvin. Both dewars start flat at the ambient temperature, around 295 K. The curves drop exponentially, but the outer dewar drops at a faster rate than the inner dewar. There is a point of inflection in the inner dewar curve, at the point where the outer dewar got below 150 K. This is where I started filling the inner dewar too; before that it was only cooling passively. Both curves asymptote to around the temperature of liquid nitrogen, 77 K.]

And here’s the Clio cooldown plot in “XKCD” style. You don’t even have to import anything, it’s already included in matplotlib, it’s just one extra line: “plt.xkcd()”.
[Image description: The same line plot as above, only I decided to put the x-axis in hours, and I used the “XKCD” style in MatPlotLib so that it looks like my plot was hand-drawn by Randall Munroe]

And we saw a herd of 5 guanacos running along the hillside as we were heading back up after lunch:

MagAO 2018A Day -1: Strike On The Way In

LATAM airline employees are striking. Luckily it didn’t affect my flight, but Katie had to take a different one (that wasn’t why she was late to dinner, that was an unrelated bus problem). Laird is now on a completely different airline, probably will get lost at sea. And our surprise mystery guest is completely hosed. So you’ll have to wait to find out who that is after he finishes the hike from Santiago.

This morning’s sunrise.
This is Patchy.

MagAO 2018A Blog Rules

Hello MagAO fans! We’re back with the 2018A run. My trip started out with a swim workout in honor of the flag of Chile:

Master’s swimming gave me a great send-off workout this morning.
[Image description: Collage: An 8-lane, 25-yard “short course” competition swimming pool with a swimmer and coach getting ready to start the workout. Below it, a swim coach standing by her workout, which is written on a white board, and the white board is standing up against a deck chair.]

Chilean Flag Workout. I got off to a good start with the blue sky with white star for unity, and swam hard in the white snow of Andes, but I only made it partway through the red bloodshed for freedom before the hour was up and it was time to get going to the airport. It was a great swim and I learned about Chile’s flag!
[Image description: A close-up of the white board with the workout on it. The workout has 3 phases, first a pre-set with fins, then the first part of the main set is a ladder on fairly fast intervals, then the body of the main set is a sequence of 50s and 100s on varying intervals. The 3 phases of the workout are drawn as the 3 main colors in the flag of Chile. And the meaning of the Chilean flag colors are written in between the sets.]

A lovely day for a swim and then a 27-hour journey from Tucson to LCO.

Now the MagAO team is in various stages of travel. Time for the blog rules for 2018A.

  1. There must be a post every day
  2. Each daily post must include a song of the day
  3. As well as the original song of the day, a cover version must be posted

Congratulations Dr. Wu — MagAO’s newest Ph.D.!

MagAO’s own Ya-Lin Wu defended his Ph.D. dissertation and is now Dr. Wu! Congrats Ya-Lin!

Dr. Wu and his happy advisor.

Ya-Lin has used MagAO to study planet formation in many ways, most recently combining VisAO data with ALMA data to study circum-planetary disks. Check out all of his papers on our Publications page.

Ya-Lin is now on his way to the University of Texas at Austin as a 51 Peg b fellow. Way to go.

Greetings from LBTI AO!

UA’s fall semester is done and the campus is nice and quiet. This means… time for an LBTI run!

I’m posting from the LBTI AO remote room in Steward Observatory. I’m helping out with driving the first shift AO for 3 nights. LBTI has two eyeballs (to use Amali’s terminology), so it requires 1 AO operator per eyeball. Tonight, I’m on SX (left eyeball).

Yesterday was the first night of the run and we were closed out due to nasty humidity. The best value last night was 99.8%. There was rain over the weekend and the clouds didn’t clear out until today.

Tonight is the second night of the run and it’s been going pretty well (so far)! I’m pretty rusty with the AO, so Amali has been bringing me back to speed. Amali made a really awesome cheat sheet for AO operations, and it’s been extremely helpful. Data collecting began at 6:30 PM. It’s been a smooth run so far with seeing below 1″ and very few problems. Hopefully this sets the tone for the rest of the run.

Clear skies ready for tonight!

The best part of observing is in the snacking. We have some fringe cookies as a good luck charm for getting null fringes. We also have these really good star sandwich cookies, just like how LBTI works!

Holiday cookies are best cookies.

We also saw something strange on the all sky cam!

CIA UFO sighting?

Anyways, a Christmas post is not complete without showing MagAO-X’s festive cheer! We have Christmas stockings pinned up on the board in front of the MagAO-X PI’s office. Isn’t it super cute???

Next year, we’ll have a fireplace, too.

And of course, a quote for tonight:
Phil: What’s going to happen to the observation run when the fringe cookies are gone?

Good luck LBTI on the rest of your run! Have a very merry christmas, everyone! Until the next blog post. 🙂
