                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Jack Dembicky
Started cooling the enclosure with the fans at 19:00, opened
enclosure/mirror covers at 20:10.
Clouds came in just before twilight and stopped observations at 04:50 this
morning.
No problems other than one minor one (see problem log) with the remote
observers Mac/Remark. There was also a serious problem with SPIcam while
showing the visiting (training) observers how to operate the instrument.
PR submitted. SPIcam was not needed tonight for observations.

 23:05  Remote Observers Mac gave a camera busy, then would not
        allow him to exit the slit viewer window on the Echelle.
        Things worked fine from here so he exited Remark and re-
        started the Echelle. This fixed the problem.
 00:15  SPIcam filter wheel and shutter would not initialize.
        Resetting instrument did not fix.                        2001157
