Keck it Up! Greetings from Hawaii!

Where am I? I am NOT actually at the telescope, which is at ~ 14,000ft on Mauna Kea Summit.
I am in Waimea, at the Keck Remote Observing site.
Today we are up early (10am… which is 4pm Notre Dame time), and going on a hike somewhere on the island and then back to the site to prepare for observing run tonight.
Why not go up to the summit? We are, but only for a visit tomorrow. At that elevation, it’s not easy to quickly adjust physically. So we are in these SWEET observer suites in Waimea. They are gorgeous and if you look closely you can see Keck Telescopes and all the other Telescopes on top of Mauna Kea mountain from here. I’ll try to get a pic
Tonight we are going to use LRIS on Keck 1. LRIS = Low Resolution Imaging Spectrometer and we will be using a multi-slit mask to take multiple spectra in the galaxy NGC 891.
(You can think of it as if the telescope were trying to look through a keyhole and you want JUST the light from that keyhole to reach you eye…)
I’ll explain more of the science latter, with pics and explanations, so STAY TUNED!
