              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out like a typical day on Mars: cold, windy, and dusty. We were able to open at 20:58 but focus was just a disaster.  This was due to the large temp difference between the mirror and the outside air that was sustained due to the louvers being closed and fans being turned off because of the dust.  Once the mirror became more equalized with outside air temp, the seeing became much less appalling at values of ~2" and improved with the night.
No problems tonight.
