Unfortunately I needed to reconfigure it (Lucas). Missed scan 222-0631 07:50UT - clock jump, but maserdelay and clkoff look stable for now (Katie). 09:15UT - Drifting got worse, reconfigured dbbc. (Katie) Missed scans 222-0914, 222-0926. Affected possibly 222-0912a and 222-0926. 09:33UT - sync error of 3 for mk5, so had to run fmset (Katie). After that eremote went unresponsive and lost connection. used the backup eremote, but nothing was happening. In the end had to restart fs. Scans missed probably from 222-0914 until 222-1037.
