                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
AzVeloScale: 580.2, 578.6; 579.4 (no change)
Overcast skies, high winds and dust kept us closed most of first half. Closed around
20:30 and opened again around 23:10. Second half cleared with mostly good seeing.
Still seeing some strange guiding behavior with TSPEC during nods in certain parts
of the sky. See PR #924.
We have "sprang" forward tonight into Daylight Savings.
