GRB 150407A: Swift detection of a possible burst
D. M. Palmer (LANL) reports on behalf of the Swift Team:
At 00:31:10, the Swift Burst Alert Telescope (BAT) detected
a possible source, GRB 150407A (trigger=637342), with marginal
statistical significance, in two consecutive images of 6 minutes
total duration.
The BAT on-board calculated location is
RA, Dec 216.603, 38.541 (J2000), which is
RA(J2000) = 14h 26m 25s
Dec(J2000) = 38d 32' 28"
with an uncertainty of 3 arcmin (radius, 90% containment, including
systematic uncertainty). As is usual for image triggers, no obvious
variation is visible in the BAT lightcurve.
After ground discovery of this pair of possible detections, a ToO
observation is planned to search for a counterpart afterglow.
See GCN#17681 for details.
