                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
Engineering tonight.
Zero'ed NA2 rotator
Pointing Model completed
02:50:37 read timed out on port LTA4 error, Alt controller Error. during middle of pointing model.
 Same problem I saw last night but tonight a little more severe.  Alt was not responding to either
TUI or talk2boxes.  Needed to power cycle the controller tonight to get it working again.
05:54 servo error too large on Az axis. Azimuth Axis stopped
Clouds were too thick to get much other than a pointing model done.  Rain was also showing up to
our west as well.  Rain sensor went off around 04:45 and I shut down for the night.
I spent most of the night working on the Wiki pages (interpreting pointing model data/plots and
removing bad data points from the models).
