BB325BM / GCN 567163

Source

GCN Report - Looks like a 0.1s - short GRB with X-ray counterpart at

RA(J2000) = 01h 51m 41.22s

Dec(J2000) = -03d 12' 30.6"

No optical counterpart with a 1m telescope in china (see GCN report).

Sent request to analysts to change phase center on 23 Aug 2013 (my time).

Observations

gogrb crashed again - so took a bit longer than expected.

Also: Looks like the check pulsar was 0437-4715 - a long way south. I can't imagine it was observed. Need to work out what it's in there.
