The ACC was removed for replacement on the 25th. The installation of the new ACC was unsuccessful due to software installation problems. The old ACC was restored to service and observations resumed on the 27th at 18:30 UT.
A power failure on the evening of the 25th caused the 27m to shutdown. Operation was restored today, but the receiver temperature had increased to 150K. The vacuum to the cryo system is currently being restored, however we do not expect calibrations to resume until the morning of the 28th Oct.
Events
Solar activity is very low.
