              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Dust delayed us from opening on time.  It finally dropped around 21:30 and we opened shortly after.
My 2nd half observer noted that the image was off about 6" (26 pixels) in the ARCTIC field.  I didn't notice anything on the telescope end out of the ordinary and not sure if it was just due to slight pointing error.
No telescope issues tonight.
