                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Opened the enclosure and started cooling around 16:15.
 We had cirrus clouds for most of the first half of the night, increasing
 towards midnight.  At around 01:00 the observer reported getting very
 almost nothing with the echelle when observing a 1.4 mag star.  I decided
 to close at this point until conditions improved.
 We gave up at 04:45 since the satellite did not show any signs of
 improvement and we were under cloudcover.
