                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: G.Saurage
 Best weather I've seen it lately: clear skies all 1st half! Even when
 observing faint objects we could guide well and get decent data (so it
 seemed). Cloud cam is still weird - the scaling is misleading, a clear
 dark sky is solid white. Seeing was poor when we opened but as the temps
 settled it significantly improved. Very productive evening for science.
 Last two nights Dataq has been very quiet. Eerily quiet.
 2nd Half Observing Specialist: J.Dembicky
 Clear all night long.  I fixed the "missing" lamp labels in TUI (actually
 in the lampswitch).
