              ------------- ACTIVITY LOG --------------
Observing Specialist:    J. Huehnerhoff
Problems at beginning of night.  Magna sensor errors prevented proper
tracking which lead to wandering and blurring of stars.  Fritz was able to
correct this although there are still some strange readings coming from
the magna sensors.
Generally good seeing with some periods of high humidity and cloud cover.

                                          off, magnasensor error would not
correct.
JH05      S      T/H     19:50   20:30    Star wandering too much to guide.
                                          Possibly more trouble with
magnasensors.
