15:00 UT Rebooted ROACHes due to bad communication with Roach 1.
21:00 UT New delay center corrections derived from the 2016 Dec 22 calibrator survey observation (using 2136+006) were sent to acc. The values for Ant 1-14 are: [0., 0., 0., -1.27, 0., 1.48, 4.26, 0., 1.5, 0., -10.24, 0., 0.] in nanoseconds

01:16 UT We were not getting good phases on calibrators, and discovered that my reboot of the ROACHes this morning left them with incorrect equalizer coefficients. This has been corrected as of 0100 UT.
01:50 UT Updated delay centers again, based on data taken today (01:01 UT).
02:14 UT Delays look good! Now going to 3C84--first scan starts 02:11 UT, on source at 02:15 UT. 3 bands
