              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
A fierce hailstorm in the afternoon caused moths to go into hiding in crevices, including one or several that clogged up the altitude motor and took a while to clean during checkout.  Skies were mostly clear by sunset but one remaining storm nearby kept us closed until the middle of twilight.  After that the night was lovely, with poor seeing initially that improved into second half, and high humidity initially that got better overnight.
