These are Heather's notes on her UKIRT run, Jan 14-15, 2010.

The first night, Jan 14th, 2010 was cloudy, with lots of bad seeing. We didn't open until 11pm hst. None of the observations (MSBs) were good (none had fwhm < 1.2 or decent extinction). The wind was very high, hovering around 35+mph the entire night, and was up in the 50s and 60s the first half of the night.

We observed the following fields, all were rejected:

• MD03:00
• MD03:02
• MD03:10
• MD03:11
• MD03:12
• MD04:00
• MD04:01
• MD04:02
• MD04:10
• MD06:11
• MD06:12

There was a bit of trickery with the MSBs- I stole MD06 from previous observing runs (we had the wrong semester installed on the summit). Chris Davis fixed this up for the next night - we had ALL the fields MD02, MD03, MD04, MD05, MD06, MD07, MD10 as possible targets for Jan 15th. This is a good thing - you want all targets in case the target you want to observe you can't (because of wind or other odd things). When MD02 was up, so was MD10, and if I couldn't observe MD02 at the start of the night because of wind, I would have gladly observed MD10 (hey, it's our time, might as well).

Jan 15th observing- no clouds, bad seeing, low winds (15mph or so). Stayed this way the entire night. Later in the night, the seeing improved a bit, became more variable, but improved to ~1.2. MD06 was unobservable due to the wind direction.

I've observed the following, all were rejected except as noted:

• MD02:00
• MD02:01
• MD02:10
• MD02:11
• MD02:12
• MD03:20 accepted
• MD03:21 accepted
• MD03:22
• MD03:01
• MD04:10
• MD04:11
• MD04:12
• MD04:20 accepted
• MD04:21 accepted
• MD06:20 cancelled halfway through because of wind
• MD04:22 accepted
• MD07:00 accepted
• MD07:01 accepted

The operator (Tim) was quite disgusted by the seeing and the clouds.. Yuck... Usually it's 0.5, and we were mostly getting 1.5, if that.
