 +
 +<note warning>​HOB+0015 will need to be shipped off for the r1761. So it's best to start recording to a third module as soon as we can, and then retrieve the data for this experiment from HOB+0015 later before shipping. Speak to the on-site person when they'​re in to switch out a module</​note>​

 +  * 0030UT Katherine switched back to bank B (XAO-1013) for bank A (HOB+0015) to be able to be shipped etc for r1761. (Liz)

 +  * 0328UT alarm sounded ALARM: error m5 -900 already off, WARNING: error m5 -906 mark5 return code 6: inconsistent or conflicting request, ALARM: error m5 -900 no scans, and then fixed itself. On closer inspection, log monitor seems to be printing information about scans from the last 2 hours in quick succession over 0321-0331UT. All outputs before and after this bracket match the schedule file. Seems to be fine now, and eremote was unaffected so appears to be a strange log monitor artefact rather than anything wrong with the experiment. Will monitor for now. (Liz) 
 +  * 0509UT Happened again. Alarm at 0457UT and 0503UT. Spoke to Jamie. Log file was reading from a tmp file which he thinks was probably the cause. Made new log file on /vlbobs/~ seems to be something was26 GB
 +2016.287.06:​05:​10 Scan name = 287-0605b interfering with the tmp file and log monitor was having to rewrite experiment history (Liz).
  
 +  *11:40 UT Autocorrelations look a bit askew in sub-bands 1, 3 and 8. I'll monitor them over the next few scans and configure the dbbc if they persist (Lucas)
