              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
My first half observer finished about an hour early.  They did not have enough time to complete another set of exposures.  I gave the extra hour to my second half observer who had logged in a few minutes prior.
No problems tonight.
