MDM Trouble Report for 2006 Jun 14

Telescope: 1.3m
Observer(s): G. Tiede, C. Bunner (Bowling Green State University)
Instrument: TIFKAM

Problem(s) Encountered:
About two of the three lost hours were due to clouds.

The other hour was lost due to a pronounced jitter in pointings
between +- 1 hour HA and between ~30 and 50 Dec.  We first noticed
a 1-2 arcsec jitter in a pointing near -1 HA +56 Dec.  It had
a frequency of ~2-3 Hz and occurred simultaneously in both RA and
DEC with or without guiding.  Subsequent pointings to > +2 HA did
not show the jitter.  Finally a pointing at +0:08 HA +56 DEC and 
-1:30 HA +32 Dec had an even larger jitter, around 5-15 arcsec
in both axes.  With only 1 hour left we closed.

We did not drive the telescope into anything nor point to low
altitudes.  The wind generally diminished during the night and
was less than 5 mph everytime we experienced the jitter.  There 
were no unusual occurances that we noted which lead up to this 
jitter.
