GCN Circular 23295

A. P. Beardmore (U Leicester),
M. J. Moss (George Washington University), K. L. Page (U Leicester)
and D. M. Palmer (LANL) report on behalf of the Neil Gehrels Swift
Observatory Team:

At 05:11:03 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 181003A (trigger=865179).  Swift did not slew immediately
to the burst due to an observing constraint. 
The BAT on-board calculated location is 
RA, Dec 52.569, -34.023 which is 
   RA(J2000) = 03h 30m 17s
   Dec(J2000) = -34d 01' 23"
with an uncertainty of 3 arcmin (radius, 90% containment, including 
systematic uncertainty).  The BAT light curve showed a single-peaked
structure with a duration of about 30 sec.  The peak count rate
was ~600 counts/sec (15-350 keV), at ~0 sec after the trigger. 

Due to an observing constraint, Swift will not slew until T0+46.3
minutes. There will be no XRT or UVOT data until this time. 

Burst Advocate for this burst is A. P. Beardmore (apb AT star.le.ac.uk). 
Please contact the BA by email if you require additional information
regarding Swift followup of this burst. In extremely urgent cases, after
trying the Burst Advocate, you can contact the Swift PI by phone (see
Swift TOO web site for information: http://www.swift.psu.edu/too.html.)
