                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 A bit windy at the start of the evening but winds (and dust) died down
 around sunset and we opened shortly after.
 Something strange happened with the DIS slitviewer (images 678-690).
 Maybe the shutter stuck closed?  It came back on it's own (after the
 guider stopped).
 No other problems.
