                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 I opened the enclosure around 17:10 under windy, but operable,
 conditions.  By 18:30 the winds had picked up to force us to close before
 we could get the telescope focused.
 The winds calmed down below closure limits and we re-opened around 19:15
 to try again.  It was still windy but the wind gusts had been below
 closure for about 20 mins now so I decided to re-open and give it a go.
 The winds remained gusty for the first half and slowly died down during
 the 2nd half of the night.
 Everything ran smooth.
