Date (UT) Project Code GCN Calibrator Check PSR Antennas Comment
2013-06-13 16:28:59 TU002AE GCNT4 J0346+5400 B0329+54   Initial test. POINT command not sent Antennas not slewed. Data correlated but no fringes (obviously)
2013-06-14 02:58:33 TU002BB GCNT28 J2339+6010 J0332+5434 SC,HN,NL,FD,LA,PT,KP,OV,BR Test observation. Target was PSR B2334+61. Correlated. Analyst says 'SC: No fringes seen'. Investigating
2013-06-23 08:54:20 TU002BE GCN558828 J1709-3525 J1717-4054   First real trigger, but accidentally left test project code in. Not observed for several reasons (mainly, a bug in the email)
2013-06-25 07:01:26 BB325BF GCN558982       Not observed. VLBA in use
2013-06-26 10:51:32 BB325BG GCN559075       Not observed. Never got a reply from vlbaops (probably not noticed)
2013-06-28 07:27:49 BB325BH GCN559221       Not observed. Operator didn't notice in time
2013-07-22 08:19:58 BB325BJ GCN563213       Not Observed. VLBA in use
2013-08-05 02:09:39 BB325BK GCN565443 J1745-2900 B1713-40 SC,HN,NL,FD,LA,PT,KP,OV,BR Observed with T+30mins. Had a bug in gogrb so was executed manually. Appears to be a 64ms burst from SGR J1745-29 (Circular)
2013-08-06 02:52:07 BB325BL GCN565562       Not Observed. Unable to observe; scheduled observing runs to 0337 UT, cutting significantly into the only available block of time of T+30. - Tony Perreault

Notes: 12 July 2013: KB logged into gygax and found no vlbagrb.py running. Gygax uptime was 8 days, so it looks like it had been rebooted 8 days before. Might have missed a few triggers, but oh well. Will update GCN configuration to make more noise when socket connection is lost. -- KeithBannister - 2013-07-11
