                               ACTIVITY LOG
(* means a trouble report has been issued or appended to)
The telescope was opened at 16:15.  The WSMR group, Mark Marley, and Sarah
Maddison tested the Amber camera on a variety of bright stars and the moon.
After a few hours of trying to locate bright stars, and checking all possible
problems, Karen Gloria and I readjusted the Tertiary mirror, and finally
got back on target.
Comments:had problems finding our first very briught star due to stuff up in
telescope orientation.  took three hours -- bit of a bummer, but these
things happen.  once orientation sorted out, things were fine.
found our first bright star, offset, focus etc..
then went to slightly dimmer source -- nothing
andother source --nothing
??
went back to initial source and it was there again.  no idea what
happened. everything else went smoothly for the evening.  amber
doesn't seem to be able to detect stars under an L mag of 3 which is
pretty pathetic.... but maybe it's a camera problme... temperatures....
whatever.
sarah & mark
nmsu.
Connie Rockosi substitued DIS for a sick SPICAM.
Comments:I asked for comment, but she forgot to send them to me.
I observed for the Lens Monitoring Run, 0957, and AR CVn.
No problems.
