2015B Day 29: Home Stretch

We might make it. Alycia has one night left, and our next and last observer arrived today (get ready for something different — more to come).

The winds were finally a bit calmer tonight, and seeing was bouncing off 0.5″ for a while — but we still ended up with some clouds after midnight. Nothing too bad, but still a little frustrating.

Two days ago we had a song about a miracle. Here’s another one of sorts — though Johnny would disagree.

I saw the CDB live at the South Dakota State Fair. This was the encore, during Johnny’s solo the old man thrashed on a golden fiddle for 20 minutes.

2015B Day 23: Ain’t Never Gonna Stop

Except when corrupt databases and/or fiber communication problems force us to do a hard reboot of the whole system, and there’s not enough time before sunrise to make it worth bringing it all back up again. Then we stop, even with stars in our eyes.

In keeping with tonight’s outrageous claims on astro-ph, we observed an Earth-sized object around a very nearby star. See Skemer and Close, 2011 for more info.

That’s Sirius B, a.k.a. The Pup, companion to Sirius, the Dog Star. Sirius is the wall of white on the left half, from us basically melting the guider CCD. You can see B along the spider spike. It is in fact Earth-sized! Even a bit smaller!
We’ve reached the point in the run where we don’t go to dinner any more. Don Hector noticed tonight, and sent plates up for Katie and me. Gracias Hector!

Since Katie just went with “not US-based” as her connection last night, I’ll just go with “Foreigner” and one of the all time classics.

If I could play guitar, I’d be in a rock band (I forgot to mention that I’ve seen Danzig live — front row right on the rail the whole show. He gave my best friend a high five.) If I could hit a curve ball I’d be chasing my cup of coffee still. The Navy wouldn’t promise me enough sea time on a fast attack, too many boring options. So I’m an astronomer now I guess. Still not sure what I’ll be when I grow up, but there’s still that one guitar.

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 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.

Here’s some more Amazing Grace.

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.
