      * 00:34UT - Drive PC failed, had to halt the schedule and restart the Drive PC.  Scans 282-0031 and 282-0037b are there, but may not be ok.

-     * 00:09 UT - Mark 5 lost connection to Field System, had to halt schedule. ​ SSReset did not reset it, did a hard reboot of Mark 5.    Mark 5 did not record ​from 22:46lost scans +     * 00:09 UT - Mark 5 lost connection to Field System, had to halt schedule. ​ SSReset did not reset it, did a hard reboot of Mark 5.    ​As it turns out, the connection to the Mark 5 has been lost.  Antenna stowed until someone can attend the telescope to fix (Imogen) 
 +     * 02:20UT - Problem with mk5ke, have to switch to mk5-2ke to record ​to that until the other mark 5 is fixed. (Imogen) 
 +     * 03:56UT - changed mk5 over to mk5-2kebegan recording again. Autocorrelations on channels 1 and 14 are really not good, but all other channels are fine for now. (Imogen) 
 +     * 06:00 UT - Autocorrelation has large spikes in bands 01 and 14. (Ellen) 
 +     * 06:30 UT - Since mk5-2ke is being used the "​clkoff"​ values are wrong and will set off alarms every scan. I changed this in the log monitor to now only beep every scan (Configure > Delay Monitoring > Audible Warning). **The delay differences must be checked manually** using the command "​clkoff-2"​ and comparing that with "​maserdelay"​. (Ellen) 
 +     * 06:30 UT - Autocorrelation still bad in those 2 bands. (Ellen) 
 +     * 1200 UT -- Edited ''​midob''​ procedure to call clkoff-2 rather than clkoff. (Dave)

      * 21:50 UT - The disc pos is already falling behind, while Ke and Ho are fine. I have noticed that Yg starts recording up to 5 seconds later than it should on some scans.
