              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
ecam needed a restart during checkout.
The night started out clear with great seeing but, towards second half, the wind really picked up.  We were near closure limits but there was never a collision and we were open all night, though with terrible seeing the second half.
No problems tonight.
