J. R. Cummings reports on behalf of the Swift science team:
At 11:33:31 UT, Swift-BAT rate-triggered on GRB 131031A (trigger 576277). No
significant source was found onboard. In ground analysis, a significant source
was found at the very edge of the BAT field of view (3% coded). The location is
RA, Dec 29.618, -1.603, which is:
RA (J2000) 01h 58m 28.3s
Dec (J2000) -01d 36' 11"
with an estimated error radius of 4 arcmin (90% containment). This GRB also
triggered Fermi GBM.
The burst was about 8 seconds long, with a multipeaked structure.
A Swift TOO request has been submitted to locate the afterglow with XRT and UVOT.
