                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
AzVeloScales: 580.9, 579.5; 580.2 (changed to 580)
Checkout: TSPEC darks are strange, banded. See
/export/images/Q1APO/UT090322/checkout/tspec_dark.0007-.0012.fits files.
Thin cirrus first half with mostly good to sub-arc seeing. Second half struggled
with clouds on and off. Seeing bouncing around 1.0"-1.3". Good pointing. Outside 1.0
mic dust counter seems improbably low.
