Once I was at an hotel in Santiago and I was trying to check my email from Tololo, where I was working at that time, and suddenly a lady from the cleaning staff saw the Tololo web page and asked me what was that …
“It’s CTIO web page the place where I work”
She looked at me and ask … “Can you do my astrological chart then?”
A bit of humour.
Humor of the day brought to you by Alberto Pasten, who takes his job looking up songs for the MagAO Blog very seriously… also he looks after the telescope 🙂
My family knows that if they want to plan something for me months in advance of when the next semester’s telescope schedule is released, they should consult a Moon phase calendar and choose a time near New Moon. You, dear readers, undoubtedly know that astronomy and not astrology dictated my schedule — infrared astronomers are usually found on telescopes during “light time,” i.e., when the Moon is up more than half the night. Light time is generally considered less valuable, because you can make observations at any wavelength when the sky is dark, but you can’t do visible light imaging of very faint objects when the sky is bright. That’s why the time before infrared astronomy is known as the dark ages (just kidding).
I was just out walking under the nearly full Moon, which drowned the Milky Way, glinted off the reflective Magellan domes, and cast my shadow upon a lit ground. So, of course, I was contemplating whether the history of science would be different if we had no Moon or two moons. What if we hadn’t had the monthly circuit of the Moon to teach us orbital dynamics and the laws of gravity and the geometry of our Solar System? Or what if we had multiple Moons that kept the sky bright all month and prevented us from observing deep space? Why, then we really would have been in the light-time dark-ages until the advent of infrared astronomy! Perhaps even worse, what if Jupiter hadn’t had bright moons that Galileo could see orbiting? How much longer would it have taken to arrive at a theory of gravity and an accurate picture of our place in the Universe?
I confess I’m being an overly smug infrared astronomer here. Tomorrow the Moon will be near a target I want to observe, and though our infrared camera won’t care, the wavefront sensor works in the visible and we’ll have to see just how flooded with photons it is. That could really make me a lunatic. See how the Moon drowns the all sky camera:
All sky camera shows Moon and only Moon.
On a separate topic, both Magellans and the duPont telescope are being run by female astronomers tonight! I will here put in a shameless plug for our other blog, Las Campanas Belles. If you don’t speak Spanish and/or don’t know about the ringing rocks, you at least have to check it out to find out why we call it that. Here are some of our observers:
Alycia Weinberger, Amanda Bosh, Jackie Faherty, and Katie Morzinski
With all this talk of the Moon and ladies, tonight’s song has to be “I wished on the Moon” by the Billie Holiday, the lady who sings the blues. Tonight, we’re not singing the blues because it’s a great night. Paradoxically perhaps, listening to Billie Holiday makes me happy.
If you really must listen to any other version (Jared), you can listen to this one, but only Billie Holiday will do for my wishes on the Moon. And I refuse to look for a parody of it.
34 days and counting. My own record is 23 nights, all alone by myself at SMARTS 0.9. So I can relate to the AO Team: you do start seeing life down the hill as a dream.
And I can say that this run has been a somewhat dark for the team: it can be either wind, clouds, hardware or whatever, but you start to miss uneventful nights. Te ones where you fall sleep of boredom.
But let’s stop bringing you down! You’re way past the half mark, just a couple of weeks and down you go! To (undisclosed high octane beverage), (undisclosed delicious snack) and (undisclosed undisclosed undisclosed).
Now to the tunes:
And (Ohhh my!) I’m going to bend the rules (just bending, both songs actually are part of the same end credits: Portal and Portal 2):
For the third day in a row, the internet connection is spotty to nonexistent. I was thinking about the early 90s, when I was a graduate student, and my advisor, Gerry Neugebauer, was the director of Palomar Observatory. He wasn’t keen on getting internet to the dome because, as I recall, he thought astronomers would waste time on their email and pay
insufficient attention to their observing and that they would come to the mountain unprepared. I think both things do happen, but that generally the benefits of connectivity are enormously high. How else could we blog?
Seriously, though, while we could come prepared with any object we might possibly want to observe, instead we can find the coordinates of objects and their finding charts when we want/need them. While we could come prepared with a library of papers on all those targets, instead we can download them when we need them. When technical difficulties arise, it’s essential to contact the experts who aren’t on the mountain. And being all the way in Chile is made much nicer by being able to call home easily with VOIP.
As if the internet weren’t already crisis enough, we’ve had technical difficulties with the AO stages last night and tonight (see last night’s blog post and my above comment about contacting experts who aren’t on the mountain and who are, in this case, in Italy).
You might we wondering, am I telling you absolutely everything?
Well not exactly. If that weren’t two crises enough, Katie and Jared are almost out of their Starbucks instant coffee. Panic could ensue before they’re resupplied (see 39 seconds in):
You can tell that’s an old movie because of all the leg room the passengers had. American Airlines executives today would be incredulous at how they could fly such empty planes;Â it’d be like the incredulity young astronomers show about how we could live without internet at the telescope.
On a happy note, the wind is low, and the clouds have moved off just north of us:
A nice looking weather page.
Since the winds are in our favor, I would post some wind music from Wind (I don’t think it’s ever been covered), but we don’t have internet access to YouTube tonight. Or email. But we are doing infrared astronomy and weirdly the connections to astronomical databases are working. Gerry, here’s a toast to your memory.
Some light clouds at sunset, but low winds. Looking good (for 2015A) for Amanda and Atom from MIT, to look at various Solar System bodies that tend to be right into the wind: We got to look to the North and East tonight because the wind was finally below our limit! Top: mid-ish night; Bottom: dawn-ish.
The internet went down but we can run everything internally just fine, so it just meant no Facebooking or emailing our families, so we carried on. (How are we still blogging? It seems the commercial internet was down but not the “Internet 2” which carries the .edu traffic so we can still get to the blog hosted on / even if we can’t get to many other sites.)
A small earthquake hit, the loop opened, we all looked around, then got back on target and closed the loop: Top — the earthquake caused the forces on our deformable mirror to ramp up (see the steep climb on the right half of the “Peak Mirror Force” plot), then the loop opened and the shell RIPd, and I force-enabled the TSS (see big red button and fake “500 m/s” wind reading) for safety — I felt it coming. Bottom: It was a 5.2 quake near Vallenar.
Then the X stage controller started acting up, and we had to call it a night. I’m going to get some shuteye here while Jared works on it for a bit with Alfio (remotely from Florence).
Update a couple hours later: X stage motor controller replaced, seems to be working. We’ll start tonight with a bunch of tests, but let’s hope that solved the problem.
From the very start of the evening: We met these burros on our way up to change the batteries in the wind monitor.
The infamous wind monitor: This exciting picture is the wind monitor
