Circular_text TITLE: GCN CIRCULAR NUMBER: 14327 SUBJECT: IPN Triangulation of GRB 130320A (long/very bright) DATE: 13/03/22 17:11:59 GMT FROM: Valentin Pal'shin at Ioffe Inst K. Hurley and J. Goldsten, on behalf of MESSENGER GRNS GRB team, S. Golenetskii, R. Aptekar, E. Mazets, V. Pal'shin, D. Frederiks, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, A. von Kienlin, X. Zhang, A. Rau, V. Savchenko, E. Bozzo, and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, and G. Di Cocco, F. Fuschino, M. Galli, C. Labanti, and M. Marisaldi, on behalf of the AGILE MCAL team, report: The long-duration, very bright GRB 130320A has been observed by Konus-Wind, INTEGRAL (SPI-ACS), MESSENGER (GRNS), and AGILE (MCAL), so far, at about 25720 s UT (07:08:40). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 192.684 (12h 50m 44s) -14.471 (-14d 28' 15") Corners: 190.889 (12h 43m 33s) -17.026 (-17d 01' 34") 190.945 (12h 43m 47s) -17.088 (-17d 05' 15") 195.164 (13h 00m 39s) -10.078 (-10d 04' 40") 195.128 (13h 00m 31s) -9.967 ( -9d 58' 00") --------------------------------------------- The error box area is 0.646 sq. deg, and its maximum dimension is 8.2 deg (the minimum one is 5 arcmin). This box may be improved. The time history and spectrum will be given in a forthcoming GCN Circular. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB130320_T25724/IPN/

Circular_text TITLE: GCN CIRCULAR NUMBER: 14328 SUBJECT: Konus-Wind observation of GRB 130320A DATE: 13/03/24 12:28:11 GMT FROM: Dmitry Frederiks at Ioffe Institute S. Golenetskii, R.Aptekar, D. Frederiks, E. Mazets, V. Pal'shin, P. Oleynik, M. Ulanov, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, report: The intense long-duration GRB 130320A (IPN triangulation: Hurley et al., GCN 14327) triggered Konus-Wind at T0=25724.822s UT (07:08:44.822) The light curve shows a double-peaked pulse with a total duration of ~20 s. The emission is seen up to 5 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB130320_T25724/ Note: periodic "dips" visible in this light curve are due to the GRB source occultation by the spacecraft structure. As observed by Konus-Wind, the burst had a fluence of (2.6 0.05)x10-5 erg/cm2, and a 64-ms peak flux, measured from T0+0.960 s, of (1.85 0.1)x10-5 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The time-integrated spectrum (measured from T0 to T0+22.784 s) is best fit in the 20 keV - 10 MeV range by a power law with exponential cutoff model, for which: alpha = -0.78 0.05, and Ep = 295 7 keV, chi2 = 85.0/93 dof. The spectrum at the maximum count rate (measured from T0 to T0+2.048 s) is best fit in the 20 keV - 10 MeV range by a power law with exponential cutoff model, for which: alpha = +0.27 0.06, and Ep = 364 7 keV, chi2 = 91.1/98 dof. All the quoted results are preliminary.
