               ------------- ACTIVITY LOG --------------
 Observing Specialists: J. Davenport
Apollo bowed out tonight due to problems with the laser. PU04 received the
extra hour.
Was able to open when humidity dropped around 10:40pm. Dewpoint sat near
closing limit with partial cloud cover until change over. Closed enclosure
at change over due to increasing cloud cover. Clouds stayed very thick and
we stayed closed second half. No problems.
