Following the IPN Triangulation of GRB 140611A (Golenetskii et al., GCN Circ # 16384),
a reexamination of the BAT image shows a sub-threshold source at the edge of the BAT
field of view at RA, Dec 349.939, -40.111 which is:
RA (J2000) 23h 19m 45.4s
Dec (J2000) -40d 06' 41"
with an estimated 90% uncertainty radius of 4 arcmin. This location is within the
IPN error box.
In BAT, this burst had two short peaks, the first 5 times brighter, each about 0.4
seconds long, separated by about 1.8 seconds. The total T90 was about 1.9 +/- 0.2
seconds. Because of the partial coding, a calibrated BAT spectrum is not possible,
but the burst appears to be in the short-hard category.
A Swift TOO is being performed.
