Circular_text TITLE: GCN CIRCULAR NUMBER: 14243 SUBJECT: GRB 130219A: Fermi GBM detection DATE: 13/02/20 19:53:04 GMT FROM: Andrew Collazzi at NASA/MSFC/ORAU Andrew C. Collazzi (NASA/ORAU) reports on behalf of the Fermi GBM Team: "At 18:35:51.73 UT on 19 February 2013, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 130219A (trigger 382991754 / 130219.775). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 303.7, DEC = +40.8 (J2000 degrees, equivalent to J2000 20h 14m, +40d 49'), with a statistical uncertainty of 1.2 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 85 degrees. The GBM light curve shows two distinct peaks with a total duration (T90) of about 96 s (50-300 keV). The spectrum is taken over the peaks, from T0+0.003 to T0+3.328 s and T+66.817 to T0+101.634, and is well fit by a Comptonized model with Ep = 396.0 +/- 21.0 and alpha = -1.11 +/- 0.02. This yields a fluence (10-1000 keV) in this time interval of (3.18 +/- 0.05)E-05 erg/cm^2. This interval is equally well fit to a Band function with Ep = 343.1 +/- 25.5, alpha = -1.08 +/- 0.02, and beta = -2.28 +/- 0.15. This yields a fluence (10 - 1000 keV) over this interval of (3.11 +/- 0.05)E-05 erg/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

Makishima, on behalf of the Suzaku WAM 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 GRB 130219A was observed by Fermi (GBM: trigger 382991754, Collazzi, GCN Circ. 14243), Konus-Wind, INTEGRAL (SPI-ACS), Suzaku (WAM), Swift (BAT), AGILE (MCAL), and MESSENGER (GRNS), at about 66950 s UT (18:35:50). 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 --------------------------------------------- Corners: 311.189 (20h 44m 45s) +51.497 (+51d 29' 50") 307.440 (20h 29m 46s) +48.611 (+48d 36' 41") 296.804 (19h 47m 13s) +37.410 (+37d 24' 35") 296.474 (19h 45m 54s) +37.565 (+37d 33' 53") --------------------------------------------- The error box area is about 2.5 sq. deg, and its maximum dimension is 17.4 deg (the minimum one is 9 arcmin). This box may be improved. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB130219_T66950/IPN/

Circular_text TITLE: GCN CIRCULAR NUMBER: 14250 SUBJECT: Konus-Wind observation of GRB 130219A DATE: 13/02/22 11:01:58 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 long-duration intense GRB 130219A (Fermi GBM detection: Collazzi, GCN 14243; IPN detection and localization: Hurley et al., GCN 14246) triggered Konus-Wind at T0=66950.352.048s UT (18:35:50.352) The burst started with a soft precursor at ~T0-0.5s which was followed, after ~65 sec of quiescence, by a harder intense emission pulse. A total duration of the burst is ~117 s. The emission in the main emission episode is seen up to ~8 MeV. As observed by Konus-Wind, the burst had a fluence of (4.2 0.4)x10-5 erg/cm2, and a 64-ms peak flux, measured from T0+81.152 s, of (2.4 0.2)x10-6 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The energy spectrum of the precursor (measured T0 to T0+8.444 s) is best fit in the 20 keV - 2 MeV range by a power law with exponential cutoff model, for which: alpha = +0.11 0.45, and Ep = 95 8 keV, chi2 = 57.2/60 dof. The time-integrated spectrum of the main emission episode (measured T0+67.792 to T0+105.984 s) is best fit in the 20 keV - 15 MeV range by the GRB (Band) function with the following model parameters: the low-energy photon index alpha = -1.08 0.07, the high energy photon index beta = -2.12 0.11, the peak energy Ep = 280 35 keV, chi2 = 90.8/96 dof. The spectrum at the maximum count rate (measured T0+79.984 to T0+81.408 s) is best fit in the 20 keV - 15 MeV range by the GRB (Band) function with the following model parameters: the low-energy photon index alpha = -1.10 0.05, the high energy photon index beta = -3.1 0.2, the peak energy Ep = 365 15 keV, chi2 = 81.3/97 dof. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB130219_T66950/ All the quoted results are preliminary.

Sugita (Nagoya U.), Y. E. Nakagawa (Waseda U.), Y. Urata, P. Tsai (NCU), K. Nakazawa, K. Makishima (Univ. of Tokyo), on behalf of the Suzaku WAM team, report: The long GRB 130219A (Collazzi, GCN 14243; Hurley et al., GCN 14246) was detected by the Suzaku Wide-band All-sky Monitor (WAM) which covers an energy range of 50 keV - 5 MeV at 2013/02/19 18:35:51.73 UT (=T0). The observed light curve exhibited two separated pulses; which are the 1st short pulse from T0+1 s to T0+3 s, and the following 2nd long pulse from T0+74 s to T0+96 s, with a total duration of 96 s. The fluence in 100 - 1000 keV was 2.06 (+0.16/-0.36) x 10^-5 erg/cm^2. The 1-s peak flux measured from T0+81 s was 5.03 (+0.57/-0.72) photons/cm^2/s in 100 - 1000 keV. Preliminary result shows that the time-averaged spectrum from T0-2s to T0+98s is marginally described as a power-law with exponential cutoff model: dN/dE ~ E^{-alpha} * exp(-(2-alpha)*E/Epeak) with alpha 1.23(-0.45 +0.39), and Epeak 502(-96 +151) keV (chi^2/d.o.f. = 33.2/24). On the other hand, the two separate pulse spectra are well fitted by different models. The 1st pulse spectrum is well fitted by a single power-law with a photon index of 2.12(+0.57/-0.37) (chi^2/d.o.f = 21.6/25). The 2nd pulse spectrum is well fitted by a GRB Band model: the low-energy photon index alpha: -1.16(-0.35 +0.49), the high-energy photon index beta: -2.5(fixed), and the peak energy Epeak: 515(-84, +145) keV (chi^2/d.o.f = 26.1/24). All the quoted errors are at statistical 90% confidence level, in which the systematic uncertainties are not included.
