              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Kosmos was down tonight but we were able to get two observers to take over B half (phew!). It was a beautiful, clear night with good seeing. UW05 was slotted for tonight (listed below) but was replaced with UW06 and UW03 who were able to use arctic and the echelle for some pretty faint targets.
