                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Jack Dembicky
Louvers opened and exhaust fans turned on at 18:55. Opened the enclosure
at 20:10 and handed instrument over to observer at 20:17.
Seeing was about 0.88 arc sec in r' at the end of twilight.  During the
first half of the night the seeing was pretty variable ranging from 1 -
2.5 arc sec, as read from the guider images.
Instrument change over occured on schedule and I did a focus (1.9 arc sec)
and pointing correction and had the instrument in the observers hands by
01:13.  No problems with the echelle tonight.
I observed 2237 this morning with seeing around 1.1 arc sec (focus) in r'
to 1.5 arc sec (actual images) in r'.
Everything ran smoothly all night long.
