First off, a special congratulations to Parker for being offered the NSF GRF award! That’s awesome. And it means that the panel that reviewed his application is just as excited about drilling holes in the Magellan-Clay telescope to mount the accelerometers as we are. It sounds a little jarring, but it’s for the Greater Good, we promise…!
The night started off as usual, with some daytime engineering followed by an excellent dinner. I didn’t take a picture, but I’m kicking myself for realizing afterwards that tonight’s dinner contained all of the components to make a California burrito. Namely, the chefs prepared a burrito-like thing (basically a beef rolled taco) and had fries and guac and such at the salad bar. Dang, talk about a missed opportunity.
This evening also offered many sightings of the family of culpeos that has taken residence in front of the lodge as the sun set in the background. Behold:
As the sun set, preparations for tonight’s observations began quickly and efficiently. For mine and Alycia’s observations tonight, we made use of a spare g’-band filter to take some data on a very special debris disk. The biggest MagAO-X fans will remember that we already have a g’-band filter installed and available in the instrument, so why is a second one necessary?…
It turns out, a longstanding problem surrounding the old g’ setup was a case of disappearing flux. Namely, there was something within the instrument that was severely affecting the throughput of green light unbeknownst to the observers who used this filter in the past. Well, we can thank Jared for spending the pesos necessary to get a green laser and do a proper test in the lab to determine the cause of the missing green light.
After some exploration with the laser we were able to determine that it was a beamsplitter in the instrument that was attenuating green light. So, our quick solution to this problem is to just bypass this beamsplitter and manually place a separate g’ filter in front of one of our science cameras. Thanks to Laird to coming up with this quick fix so that we could execute MagAO-X’s best observations at 527 nm! “The target audience will hate love it.” “Who’s the target audience??” “People with eyes…!”
Meanwhile, I thought I’d highlight a really cool picture taken by our new Leiden-based collaborator (and Master’s student to Sebastiaan) Eugenia Maria. Great shot!
We’ll end tonight with a fun challenge. Parker claims there are 5 vizzies in this photo, can you find them all?
The quotes in this post are from the move Argo which I watched on one of the long plane rides recently (thanks to Katie for the suggestion). It’s a historical flick about how CIA operatives were able to rescue US embassy hostages in Iran by masquerading as Canadian filmmakers. Would recommend!
