              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
DIS temps @20:10 206, 192
Clouds kept us closed for the entire night.  My observer neede a min of 2hrs of clear sky by 2:30 but that didn't happen so they gave up early.
Russet attempted to move the tert to BC1.  She was successful but it took her a couple attempts to get there so I accounted that as equip loss time.  It showed clamped but TUI reported ?. She was able to get signal so that was good.
DIS temps @05:20 213, 185 (Dome closed all night but louvers and fans on)
Intex fans left on and louvers left open with door open to help cool int level during the day.
DIS temps @06:10 205,185 (Dome open for 50 mins)
I noticed when closing tonight that the bottom louver by DIS did not open.
A fan to blow some air towards the DIS cryros might help.  I noticed the air from the door seemed to just go down the stairwell and it was warmer over by the DIS cryros during checkout.
