                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
Mounting TripleSpec in the afternoon triggered a vacuum alarm. Nick came up and
determined it was a bad gauge, but TSpec is offline until Monday when daycrew can
investigate further.
Humidity rose a few times but remained low enough to stay open and allowed the NMSU
group to use the eyepiece, Echelle and NICFPS during first half. Second half was
very productive as well. One momentary glitch with dcam where we got a vertical
string of stars, see dcam0257. But the following image was fine. No telescope
problems, tertiary moved twice nicely.
