     1These are Heather's notes on her UKIRT run, Jan 14-15, 2010.

     3The 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.

     5We observed the following fields, all were rejected:
     6
     7 * MD03:00
     8 * MD03:02
     9 * MD03:10
     10 * MD03:11
     11 * MD03:12
     12 * MD04:00
     13 * MD04:01
     14 * MD04:02
     15 * MD04:10
     16 * MD06:11
     17 * MD06:12
     18
     19There 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).

     21Jan 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.

     44The 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.
