Summary
----------------------------------------------------------------------


another clear, photometric night. crazy temperature inversion with 2-4 C difference between 2m and 30m temps all night. this wreaked havoc with the DIMM seeing which ranged from 1" to 4" at times. however, by keeping the louvers closed we were able to mitigate the worst of the dome seeing. mirror alignments held pretty steady considering and we had good IQ at the end of the night with EE50 1.5" or less.

the only glitch was not being able to position the guide probe when setting up for MOS. otherwise a productive night with accepted blocks for the following programs:
