-     * 04:24 - disk_pos has been drifting. As of now ~80 GB deficit. (vk)+     * 04:24 UT - disk_pos has been drifting. As of now ~80 GB deficit. (vk
 +     * 06:14 UT - mk5 crash. Missed scans: 162-0614 - 162-0631 corresponding to 58 GB deficit. (vk) 
 +     * 11:14 UT - Log monitor reported the antenna stuck but everything looked completely fine (everything was green). I checked onsource and it reported that it was tracking so I'm not sure what happened. Scan 1114a may be affected. [As a side note, I noticed that this scan was meant to start at 11:14:13 but in fact didn't start till 11:14:21! And since the total scan length was less than a minute, this is a terrible percentage lost! (Ellen) 
 +     * 11:43 UT - Disc pos ~ 200 GB behind! (Ellen)

      * 01:01 UT - Schedule starting. Missed scans 162-0040 - 162-0058 corresponding to a deficit of 54 GB (vk)      * 01:01 UT - Schedule starting. Missed scans 162-0040 - 162-0058 corresponding to a deficit of 54 GB (vk)
      * 01:10 UT - Halting schedule to restart DBBC. Resuming at 01:19 UT. Missed scans 162-0110b to 162-0118 (vk)      * 01:10 UT - Halting schedule to restart DBBC. Resuming at 01:19 UT. Missed scans 162-0110b to 162-0118 (vk)
 +     * 08:06 UT - pps_delay has jumped from 61950 to 61949. Seems stable for now (vk)
 +     * 11:25 UT - pps_delay slowly started drifting again. At 11:31 I gave up hope that it would stop and so halted the schedule to restart the DBBC. Schedule resumed at 11:35. Scans missed: ​ 162-1132 and  162-1133. Scans 162-1135b and 162-1136a only started recording halfway through so is going to be bad. This corresponds to ~20 GB missing. (Ellen)
 +     * 11:47 UT - ~170 GB lost due to missing scans but disc pos is about 20 GB AHEAD?! (Ellen)
