TITLE: GCN CIRCULAR
NUMBER: 9098
SUBJECT: GRB 090405: Fermi GBM Detection
DATE: 09/04/06 16:34:41 GMT
FROM: Adam Goldstein at Fermi-GBM/UAH
A. Goldstein (UAH) reports on behalf of the Fermi GBM Team:
"At 15:54:41.34 UT on 05 April 2009, the Fermi Gamma-Ray Burst Monitor
triggered and located GRB 090405 (trigger 260639683 / 090405663).
The on-ground calculated location, using the GBM trigger
data, is RA = 226.7, DEC = -5.6 (J2000 degrees,
equivalent to 15h 07m, -05d 37'), with an uncertainty
of 9.9 degrees (radius, 1-sigma containment,
statistical only; there is additionally a systematic
error which is currently estimated to be 2 to 3 degrees).
The angle from the Fermi LAT boresight is 70 degrees.
This burst was also independently detected by INTEGRAL SPI-ACS.
The GBM lightcurve consists of one peak with a duration of about 1.2 s.
Since the source is weak, the time-averaged spectrum is poorly
constrained."
