Observing Specialists: G.Saurage
Az Vel Scales: 586.9, 590.9 avg 588.9
Cloud line moving in from the NW around sunset produced some rain in the
basin and kept us closed for a little while at the beginning of the night.
While moving the tertiary from NA1 to NA2 at the switch to 2nd half the
tertiary clamps failed to close properly the first time. The second
attempt gave no error messages.
