              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out beautiful!  It's the first time I've been able to open the dome for cooling in weeks. WY02 was able to sue all of their time under gorgeous weather, but CU01 was hosed and with all the wind, clouds, rain, and fog, were never able to see Venus.
TUI crashed at about 8pm (WY01 continued to take their cals during twilight)  which was due to a bug with the truss lamps, however Fritz was able to quickly fix it.
