MDM Trouble Report for 2002 Mar 4

Telescope: 2.4m
Observer(s): Vestergaard (OSU)
Instrument: CCDS

Problem(s) Encountered:
Starting around midnight and lasting for about 3 hours the
telescope tended to jump in the East - West direction.
It would do this both when I was guiding (resulting in
loosing both position, the guidestar, and the exposure) and 
when I was not guiding. I was pretty close to Zenith for 
most of those 3 hours, so the reason is not clear to me. 
However, it must clearly have been problems with the tracking 
because the initial jump of the telescope was always some 
10-30 arcsec east and then it would often skid around (jump 
east, then a little west, then east again). Once I was in the 
midst of centering my object on the slit (small offsets) when 
it happened. It was hard to `hold' the telescope with the 
keypad. The winds were the same as earlier and later.
