Quick run-around JCMT! 

This happened on the first night I was there but the audio was so bad due to the noise of the telescope I was putting off doing closed-captions for it until now. Pardon the giggling, I’m excited plus the altitude hohoho. And apologies for it stopping abruptly, the camera ran out of memory(!). 

Ewww I just has a (tiny-thankfully) nosebleed, probably caused by the lowish humidity catching up with me (17% outside now), although in the control room it’s 40% humidity so I should be okay from now on!

theformerastronomer replied to your post “Will you be going to other observatories on Mauna Kea? An insider’s view of UKIRT would be cool!”

Ahhh! Thor is in one of Darren Baskill’s pictures! He was my favourite TO ever :-).

YES! I haven’t met him but I hear he’s a pretty cool guy! :D With a name like Thor you’d have to live up to it and I hear he does! 

Here’s the way I had it explained to me. With the reduced oxygen, bicarbonates build up in your blood. The kidneys remove the excess bicarbonate from restore the blood’s pH level. (Not a squish science guy either!)

That’s cool! :D
squish science, omg yes!

Fantastic! :) I worked in the delay line calibration on the MWA in Australia. It’s now 25% higher resolution because of my work

Omg that’s so cool! And congrats that’s a massive improvement!

I was told that when the JCMT mirror/antenna (I never quite know what to call it!) was being delivered, it was hijacked by pirates. My first reaction was, "Right! Pull the other leg!" But I've always wondered. So, what have you heard about that story?

I’ve just asked our TSS and he said yes it’s true! The telescope - mirror and carousel, the entire structure - was delivered from the Netherlands, and held to ransom by pirates for about three weeks before it was finally delivered! 

tac-star Asked:
I haven't been able to get a good answer to this one -- but I have a feeling I'm going to feel really silly when I find out. The submillimeter telescopes all seem to be idle over the day. But, submillimeter telescopes operate below IR wavelengths. What keeps you from operating over the daytime?

Not a daft question at all, neither is the opposite question (why do submm telescopes work during the day) :D. To answer the part you already know, the Sun isn’t very bright at all in the wavelengths we look in, so it’s always “night” for the sub-millimetre in terms of light, hence we aren’t restricted 

There are a few reasons why we don’t observe all day, that’s because 1) with the doors open, the primary mirror would heat up. This would cause it to warp a bit, which we could compensate for in some cases, but when it came to night time we’d have to wait a long time for the mirror to thermally relax.

2) (Have I got this right?) Even if the weather looks good, apparently it’s really hard to get a good pointing? Even if the atmosphere is perfectly transparent to submm light, which is awesome if it is we love that, the atmosphere can be a tad granular during the day, causing the submm to twinkle. This means when we try and calibrate the telescope with a pointing by finding, say, Mars, it moves all over the place, and there’s just no point in observing since all your observations would be smeared and messy. So we can get all the light, just it doesn’t sit still.

3) Money, sadly :( nowadays we can switch for extended observing in the morning for a few hours, we switch over control to the team in the Joint Astronomy Centre in Hilo when the weather is good, but that finishes about 10/10:30/11. 

All the telescopes have a day-crew of engineers who come up and test/update/fix everything that’s needs it during daylight hours, too and they are the most important people on the telescope team. I haven’t met any of the team sadly, but they always get everything done because they’re the real pros - and as a side-note someone even curls up the ethernet cables too (which I felt bad about when I noticed so I tried to do the same when I leave I’m so sorry if everything’s a mess aaa). The day crew makes everything possible :)

astronomers got tired after watching the moon go around the earth for 24 hours so they decided to call it a day

Yes that is enough noms, haha! I made a dodgy choice with this username because when you see the name it’s easy enough to understand esp for the internet audience but /telling/ meat-space folk the URL is quite a challenge

Milky Way centre and the glow of Kīlauea from Mauna Kea, Hawai’i on my Flickr.
The Pretty is the Milky Way centre. The red glow is from lava in the distance. It just happens to align with the foreground extinct cinder cone!  I got soooo lucky with this shot, I still have to improve it a tad in post, too. I can’t wait to do it :wiggles:

If the weather stays good (which it might not) then we’ll be doing long observations and the TSS may show us the game Kerbal Space Program - I’ve been avoiding it forever because I know I would become addicted but looks like now’s the tiiiiimeeeee…
