SUBJECT: GRB 160521A: a long GRB detected by INTEGRAL
DATE: 16/05/21 04:45:52 GMT
FROM: Sandro Mereghetti at IASF-Milano/INAF
S.Mereghetti (IASF-Milano), D.Gotz (CEA, Saclay), C.Ferrigno, E.Bozzo,
L.Di Gesu' (ISDC, Versoix), and J.Borkowski (CAMK, Torun) on behalf of the
IBAS Localization Team report:
a gamma ray burst lasting about 160 s has been detected by IBAS in the
IBIS/ISGRI data at 03:37:20 UT of May 21, 2016.
The refined coordinates (J2000) are:
R.A.= 129.7108
DEC.= 46.9142
with an uncertainty of 1.5 arcmin (90% c.l.).
The burst had a peak flux of 0.8 counts/cm2/s (20-200 keV, 1-s integration
time) and a fluence in the same energy range of about 1.2e-6 erg/cmq.
A plot of the light curve will be posted at

SUBJECT: GRB 160521A: 15 GHz detections and upper limit from AMI

We observed the INTEGRAL/IBIS GRB 160521A (Mereghetti et al., GCN 19442)
with the AMI Large Array at 15 GHz on 2016 May 24.62, May 27.52, and Jun
03.61 (UT) as part of the 4pisky program. We detect a transient radio
source (RA=08:38:51.3 +/-6 arcsec, Dec=+46:54:21 +/-24 arcsec) within
the INTEGRAL error circle at 266+/-36 uJy and 133+/-29 uJy in the first
two epochs, and obtain a 3sigma upper limit of 93 uJy in the third epoch.
We thank the AMI staff for scheduling these observations. The AMI-GRB
database is a log of all GRB follow up observations with the AMI, and is
available at http://4pisky.org/ami-grb/.
