- Duration 300 s. Got IR detections.
Best XRT position:
RA (J2000): 12h 34m 5.22s
Dec (J2000): +27d 57' 02.9"
With an uncertainty of 1.9 arcsec (radius, 90% confidence).

NOT got an optical position:
with an uncertainty of 0.5''
Emailed analysis to set the NOT position as the phase center on 16 Jan 2014.
Requested not delete VFASTR 16 Jan 2014.
V-FASTR data corrupted. The data contained lots of dropped packets which was raising lots of spurious candidates. From Adam Deller:
Someone thought this machine was just a file server and moved it away from the fast correlator switch to a different switch. Hence, crap network performance and many dropped V-FASTR packets, I suspect.
I will email the analysts and ask if they can recorrelate BB325BX. Hope the disk packs are still around.
Bad news - the packs were released on Friday. So this dataset is a bust, sorry Keith. Bad timing.
So the V-FASTR data for this run is useless. The correlated data should be OK though.
According to the observing log, our obs started ~22 minutes after the BAT trigger. According to the XRT light curve, most of the action was missed by then.
