                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
Az Vel Scales: 575.3, 578.7 avg 577.0
Hazy but mostly clear at sunset. We had thin clouds all night; thickening
enough around 3:00 to make guiding fail. We weren’t getting any real
signal after that. No telescope problems.
