2015B Day 24: From Alberto

Things are going well this week and the weather is ok.
Waiting for the new star wars movie, here we go!!!


The song of the day, speaking of Jukebox Heroes and Blockbuster movies: Hero by Chad Kroeger:

And a picture of myself for Alberto:

!Hola! I like the videos.

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 22: Holes worn through

Day 22, Kim is helping a lot, Kate R. arrived today, Kate F. arrives tomorrow, astigmatism is fixed, MagAO is well.

Thanks Gabriel, Hugo, Emilio, Pato, Felipe, Victor, Povilas, Alberto, Hernan, Mauricio for fixing the focus offset to fix the astigmatism
We aren’t giving up the ship

Yesterday’s song of the day was by Dawid Podsiadlo from Poland. Today’s song of the day is by another overseas David, Davido Adedeji Adeleke from Nigeria:

Ok this spider is really big but we are too scared to get closer and I am holding the camera down below Jared’s head but trust me it was huge

2015B Day 21: Surprise Surprise

While it is Day 21 of operations for the MagAO team, it’s only Night 2 of MagAO observing for me! But it is my Night 9 of observing in total: I just finished a seven-night run with the Gemini Planet Imager and mountain-hopped over from Cerro Pachón to Las Campanas on Sunday to join Katie, Jared, and company.

While last night and tonight involved re-orienting my mental muscles to speak Adaptive Secondary, our visiting observer, Julio, was busy flexing the rotational and wave-front sensing muscles of MagAO. With nice stable conditions (0″.5-0″.6 seeing) and clear skies, faint and off-axis targets were fair game — after some collective brainstorming on how best to set up rotator angles. (Those are always so tricky.) And thus Surprise #1: Closing the loop on a target of R~15.5 with only 16 photons per subaperture? You got it!

Surprise #2: My journey between mountaintops involved an astonishing realization for me yesterday. The past two times I’ve come up to Magellan from La Serena, I’ve always immediately dozed off in the car — typically right after leaving La Serena’s town limits. The drive is about 3 hours from La Serena to Las Campanas Observatory, along the Panamericana Norta/Ruta 5:

One day of travel (about 5-6 hours): Start at Gemini Observatory (Cerro Pachón, bottom), take carry-all bus to La Serena, take observatory transport up to Las Campanas (top)
One day of travel: Start at Gemini Observatory (Cerro Pachón, bottom), take carry-all bus to La Serena (about 2 hours), take observatory transport up to Las Campanas (top; about 3 hours).

However, this time, I stayed awake quite a bit longer, and discovered to my delight that the route takes us right along the coast. I wondered at the time if it was an alternate way compared to my previous journeys (I’ve only woken up in the mountain terrain regions before). I wasn’t speedy enough to take a photo myself, but this is the gem of an area I glimpsed in my drowsy state:

Shortly thereafter, my nocturnal schedule won out and I fell right back asleep in the car. Jared and Katie assured me that the drive is, indeed, the usual route — so next time I will try to stay awake even longer. Who knows what I will discover then!

One nap later, I arrived to the observatory just before dinnertime. The late timing meant I wasn’t able to submit a night lunch request. However, I figured there was an ample supply of fruit, cheese, and cereal to tide me over at the telescope, and wasn’t too worried. Near midnight, Katie kindly realized I hadn’t a night lunch of my own and offered me a fabled LCO Empanada, as she and Jared had some of their own to share. However, Mauricio overheard the exchange, and sprung to action: “Oh, you don’t have a night lunch? Do you want an empanada? Don’t worry — I know a guy.” He made a quick call, and a few minutes later Jorge dropped by from the Baade telescope with a delivery (Surprise #3):

The photo doesn’t even quite do it justice (though the dramatic effect is enhanced by Google Camera’s “Lens Blur” feature — incidentally, a super fascinating read if you enjoy learning about image processing!) Mine had seafood stuffing — so delicious. I was very thankful for everyone’s generosity! And it’s no wonder why the New York Times has written articles about this famous food.

Surprise #4: I think springtime is moth season here. A few adventurous and particularly robust ones have wandered into the control room, flittering about the lights and casting bird-sized shadows on our keyboards while we work. Unfortunately, their dive bombs can be a bit distracting… Especially when inter-species warfare occurs right overhead. At one point, something that looked awfully like a (non-poisonous, Hernan assured us) scorpion descended from the overhead lights and settled on the ground right next to our chairs.

It seemed one of the moths and the scorpion duked it out in the overhead lights, and the vanquished scorpion took a tumble down toward us. Or… Perhaps it was a flying scorpion? Unfazed, it skittered away while we discussed the finer points of whether or not the scorpion family has an airborne subspecies in South America. Until…

Katie: “It seemed like it was flying, and then I saw it run away…”
Jared: “Hmm, where did it go? Where was it headed?”
Katie: “Right toward you!”
Jared: “… Wait, what?”

Then this happened:

Jared and Julio lunge underneath the desk to examine the mystery insect. (Sorry, I only got a blurry action shot!)
Jared and Julio lunging underneath the desk to examine the mystery creature. Sorry — could only get a blurry action shot!

Flashlight in hand, Jared and Julio spotted our insect (or arthropod?)  friend beneath the desk, presumably until it crawled away toward greener, moth-free pastures. I’m not sure we ever answered the question of flying scorpion existence though — we await confirmation from our entomologist readers.

We had two more surprises last night — a little family of baby birds nesting right outside the control room door (pleasant surprise), and some baffling sources of astigmatism that became increasingly worse throughout the night (not-so-great surprise) — but those might be best saved for later pending photographic evidence and further investigation, respectively.

And to close out the past 48 hours filled with unforeseen, fortuitous, and/or unpredictable things, here is an appropriately titled song:

EDIT! I have been informed that the 2015B music rules are a little different this time around, and I need to come up with a different selection — one that is somehow related to the previous post’s music (Jared’s choice of Mother by Danzig).

Okay, so here is my alternate selection:

Unnecessarily Complicated Explanation: I actually haven’t heard the band Danzig before today, but the name sounded familiar. (Turns out Danzig is so named for the surname of the lead singer, Glenn Danzig.) Google tells me that Danzig is also an alternative name for the city of Gdańsk in Poland (which incidentally has a rich history, particularly in both the first and second World Wars). This made me curious about which popular songs people in Poland are listening to right now, so I looked up their current top 10 charts. And the first song in Polish on that list is W Dobra Strone (“In the Right Direction”) by Dawid Podsiadlo. It’s pretty catchy!

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.
