              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out clear but with high dust. While it was gusty in the afternoon, the dust remained even after the winds died down. By 12 deg twilight the dust was still too high to open and we called it.
No problems tonight.
