2015B Day 20: Still Here

I’ve been here for more than 3 weeks. 2 more to go.

This time we have actual Danzig, singing to the various mothers.

2015B Day 19: Vanessa was here?

Last night we lost ~5 hours to the X-stage problem. Tonight we lost about an hour (of perfect weather and amazing seeing) due to the BCUs locking up and the shell doing that thing where it panics. Yet we still squeezed in some good data for our own projects. Was Vanessa Bailey here? She has the distinction of doing the most with the least bit of MagAO, as far as I can recall. On two separate occasions she had a half night with MagAO and lost most of her time due to instrument problems. Once it was the “wait for AO” problem that took us about 3/4 of her half-night to diagnose, and once — was it the Clio motor failure? They’re all starting to blur together… …yet she still managed to get data on her top targets in just 1 hour and discover a planet with some of her bare-minimum MagAO time. Well, now she’s graduated and moved on to GPI, but MagAO still misses her, and tries to bring some of that Vanessa essence back to the telescope…

A beautiful night with 0.41” seeing, a bad time to have instrument problems (again).
A quiet Arizona/MagAO night.

MagAO is happiest when it has the most photons. It must be all that radiation pressure that keeps the mirror flat…right? When we opened the loop for the last time tonight, we were looking at the 2nd brightest star in the sky. Here’s the nice flat wavefront on the pyramid pupils:

Many photons makes the AO happy

Um, well I am not a fan of the noise and shouting in yesterday’s song of the day… All I can think of is another song with shouting… and also Shakira!:

2015B Day 18: #LifeOnMagAO

We seem to have more problems on *our* nights than on any others. I guess that’s a great customer service policy, but we’re really in this to do our own science. So, the X stage is dead (again) and it says “Morzinski” on the schedule. We spent the first half of the night fairly desperately trying to get the motor to move to just the right spot so that we could take our observations. The problem is the optical encoder (we think — if you’re keeping track that’s about the 11th explanation we’ve come up with). This means the motor doesn’t know where it is, so I spent 3 hours out on the platform pressing “go” and the “stop” as fast as I could to try to get it to hop to the right spot.

It finally landed exactly where we want it, and it is now turned off never to be turned on again. Or at least until we can safely troubleshoot it. For now, we are in a scientifically productive state and we’re leaving it there.

Just in case you ever wondered how this is handled around here.

2015B Day 17: #LifeAtLCO

Jackie and the DTM Tweeps have been putting up signs about Tweeting #LifeAtLCO.


MagAO doesn’t Tweet (yet) [“Loop is open. Shell RIP. #LifeAtLCO”] but today it’s time for a lifestyle post:

Some flowers for the various mothers.
Lifestyle shots. #LifeatLCO

And with TJ here to run all 3 cameras at once, Jared and I get a nice break #LifeAtLCO

Yesterday’s song was from Maverick. Here is the Maverick choir singing Amazing Grace. It’s pretty swinging and there are a lot of great singers in there. Enjoy!

2015B Day 16: We had . . . get this . . .clouds tonight

Sigh. And also, our X stage started doing that thing again tonight. Laird, we may have to have one of our wonderful cable routing bonding sessions. You know, the kind where I hold the flashlight for 5 hours while you talk to yourself with your head inside the instrument. I can’t wait.

Since we had clouds, I bailed on the control room and went down to the astronomer’s lounge. Much comfy.

I got a new laptop on this run. It took a long time to come after ordering it, so Amali brought it down for me. It’s got a touch screen and everything.

A horrible sight.

Here’s another Clint Black song. It also describes TJ’s last couple of nights.
