TITLE: GCN CIRCULAR
NUMBER: 9804
SUBJECT: GRB 090814C: Fermi GBM detection
DATE: 09/08/14 15:40:30 GMT
FROM: Andreas von Kienlin at MPE
A. von Kienlin (MPE) reports on behalf of the Fermi GBM Team:
"At 08:49:41.22 UT on 14 August 2009, the Fermi Gamma-Ray Burst Monitor
triggered and located GRB 090814C (trigger 271932583 / 090814368).
The on-ground calculated location, using the GBM trigger
data, is RA = 332.5, DEC = 58.9 (J2000 degrees,
equivalent to 22h 10m, 58d 54'), with an uncertainty
of 5.5 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 61 degrees.
This burst was also independently detected by INTEGRAL SPI-ACS.
The GBM light curve consists of a single peak
with a duration (T90) of about 0.25 s (8-1000 keV).
The time-averaged spectrum from T0-0.064 s to T0+0.192 s is
well fit by a power law function with an exponential
high energy cutoff. The power law index is -0.39 +/- 0.11 and
the cutoff energy, parameterized as Epeak, is 790 +/- 120 keV
(C-stat 500 for 479 d.o.f.).
The event fluence (8-1000 keV) in this time interval is
(6.6 +/- 0.4)E-07 erg/cm^2. The 0.64-sec peak photon flux measured
starting from T0 s in the 8-1000 keV band
is 9.1 +/- 0.5 ph/s/cm^2.
The spectral analysis results presented above are preliminary;
final results will be published in the GBM GRB Catalog."
