Westerbork (Tony Foley at Tue Nov 23 14:35:07 MET 1999) Minor failures

Stopped observing early as all scans after 11:25 are out of Hour Angle range. Total power in array lost from 09:32 to 09:40 UT (delay sprang to test setting). Tape lost vacuum at 10:04 so the end of pass 6, all passes 7 and 8 are lost. Restarted with pass 9 at ~10:55UT. Cause of vacuum loss was dirt from the tape blocking vacuum sensor.
