     * Maser maintenance at both Katherine and Yarragadee currently, hence Brett is not at the Observatory. Warren is at Mt Pleasant Tuesdays to Thursdays and occasionally Mondays.     * Maser maintenance at both Katherine and Yarragadee currently, hence Brett is not at the Observatory.

 +      - High tsys values due to RFI
  
     * R4734 - Yarragadee: consistent offset between mark 5 and other computers of 0.1 - 0.4 visible in fmset with no sync error, could not be fixed. Caused by power failure affecting GPS receiver (new UPS installed) - had to change to Hobart'​s. Fixed itself 4+ hours later. Is there any way to fix this other than hope?     * R4734 - Yarragadee: consistent offset between mark 5 and other computers of 0.1 - 0.4 visible in fmset with no sync error, could not be fixed.

Monitor make note of how many scans were affected by high tsys values.+    * High system temperatures - run systemp12 again to make sure it wasn't just one dodgy reading.
