Circular_text TITLE: GCN CIRCULAR NUMBER: 14271 SUBJECT: GRB 130307A: Fermi GBM detection DATE: 13/03/08 05:19:20 GMT FROM: Veronique Pelassa at UAH V. Pelassa (UAH) reports on behalf of the Fermi GBM Team: "At 03:01:44.47 UT on March 7 2013, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 130307A (trigger 384318107 / 130307126). The on-ground calculated location, using the GBM trigger data, is RA = 153.7, DEC = 18.3 (J2000 degrees, equivalent to +10h 12m, +18d 16'), with an uncertainty of 3.3 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 67 degrees. This burst was also independently detected by INTEGRAL SPI-ACS. An IPN triangulation will be issued in a forthcoming circular. The GBM light curve consists of a single pulse with a duration (T90) of about 0.4 s (50-300 keV). The time-averaged spectrum from T0-0.64 s to T0+0.032 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -0.78 +/- 0.06 and the cutoff energy, parameterized as Epeak, is 1670 +/- 350 keV (Castor statistics 816 for 728 d.o.f.). The event fluence (10-1000 keV) in this time interval is (1.43 +/- 0.05)E-06 erg/cm^2. The 64-msec peak photon flux measured starting from T0+0.064 s in the 10-1000 keV band is 9.9 +/- 1.1 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

Pal'shin, D. Frederiks, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, K. Hurley and J. Goldsten, on behalf of MESSENGER GRNS GRB team, V. Connaughton, M. Briggs, C. Meegan, and V.

Gehrels, H. Krimm, and D. Palmer, on behalf of the Swift-BAT team, G. Di Cocco, F. Fuschino, M. Galli, C. Labanti, and M. Marisaldi, on behalf of the AGILE MCAL team, report: The short-duration GRB 130307A was observed by Fermi (GBM: trigger 384318107, Pelassa, GCN Circ. 14271), Konus-Wind, INTEGRAL (SPI-ACS), Swift (BAT), AGILE (MCAL), and MESSENGER (GRNS), at about 10904 s UT (03:01:44). The burst was outside the coded field of view of the BAT. We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 155.996 (10h 23m 59s) +22.998 (+22d 59' 53") Corners: 154.692 (10h 18m 46s) +22.026 (+22d 01' 32") 155.790 (10h 23m 10s) +23.534 (+23d 32' 02") 157.288 (10h 29m 09s) +23.852 (+23d 51' 08") 156.204 (10h 24m 49s) +22.463 (+22d 27' 46") --------------------------------------------- The error box area is about 1.6 sq. deg, and its maximum dimension is 3.0 deg (the minimum one is 1.3 deg). This box may be improved. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB130307_T10908/IPN/
