.@LindaLy79 Excellent question! Here is the best way to know: mkwc.ifa.hawaii.edu. It's dedicated just to Mauna Kea weather
CIT observers will work with MOSFIRE tonight. And UCI observers will work with DEIMOS. Sun set 06:36:00pm rise 06:33:00am
Observers from CIT will use MOSFIRE on Keck 1, while on Keck 2, UCI observers will use DEIMOS. Sun set 06:36:00pm rise 06:34:00am
On Keck 1, we have NASA observers using MOSFIRE. On Keck 2, we have CIT observers using DEIMOS. Sun set 06:35:00pm rise 06:34:00am
UCSC observers will use MOSFIRE on Keck 1, and ANU observers will use DEIMOS on Keck 2 tonight. Sun set 06:35:00pm rise 06:35:00am
