					ACTIVITY LOG
	The enclosure opened this evening at 20:20, clear skies, low wind,
and low dust. Gerhardt Muerer started this evening with SPIcam, no
problems, observing seemed to go smoothly all night.
	The rotator was re-zeroed with minor offset. All computers and
hardware performed without incident, except that the Gerhardt found the
thumbwheel bug in REMARK 2.4.1a which crashed his Mac early on. This
bug has been fixed in release 2.4.2, which is being tested here and
elsewhere, and will be released as recommended version soon.
	When focusing for the lens monitoring program, I aborted an
exposure on SPIcam, then all following exposures (2 focus) gave only
bias exposures! I exited from SPIcam and restarted it. After that
it seemed OK and things went smoothly. I observed one lens object in
two filters.
