Circular_text TITLE: GCN CIRCULAR NUMBER: 9056 SUBJECT: GRB 090328B: Fermi GBM Detection DATE: 09/03/30 18:06:00 GMT FROM: Adam Goldstein at Fermi-GBM/UAH A. Goldstein (UAH) reports on behalf of the Fermi GBM Team: "At 17:07:04.94 UT on 28 March 2009, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 090328B (trigger 259952826 / 090328713). The Fermi Observatory executed a maneuver following this trigger and tracked the burst location for the next 5 hours, subject to Earth-angle constraints. The on-ground calculated location, using the GBM trigger data, is RA = 155.72, DEC = +33.40 (J2000 degrees, equivalent to 10h 23m, 33d 24'), with an uncertainty of 7.94 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 74 degrees. The GBM light curve consists of a single bright peak with a duration (T90) of about 0.32 s (8-1000 keV). The time-averaged spectrum from T0-0.13 s to T0+0.13 s is well fit by a Band function with Epeak = 1967.0 +/- 701.0 keV, alpha = -0.92 +/- 0.06, and beta = -2.48 +/- 0.66 (chi squared 452.6 for 482 d.o.f.). The event fluence (8-1000 keV) in this time interval is (9.61 +/- 0.31)E-07 erg/cm^2. The 0.064-sec peak photon flux measured starting from T0+0.0 s in the 8-1000 keV band is 29.83 +/- 2.38 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

Circular_text TITLE: GCN CIRCULAR NUMBER: 9065 SUBJECT: GRB 090328B: MASTER-Irkutsk prompt optical short burst observations DATE: 09/04/01 08:47:35 GMT FROM: Vladimir Lipunov at Moscow State U/Krylov Obs K.Ivanov, S.Yazev, Irkutsk State University E. Gorbovskoy, V. Lipunov, V.Kornilov, A.Belinski, N.Shatskiy, N.Tyurina, D.Kuvshinov, P.Balanutsa, V.V.Chazov, P.V.Kortunov Sternberg Astronomical Institute, Moscow State University A. Tlatov, A.V. Parhomenko, Kislovodsk Solar Station of the Pulkovo Observatory V.Krushinski, I.Zalognikh, T.Kopytova Ural State University, Kourovka There are 6 MASTER Very Wide Field cameras located at Kislovodsk and Irkutsk with common FOW = 6000 square degrees (http://observ.pereplet.ru/). One of the two MASTER Very Wide Field Cameras located at Irkutsk (D=50 mm, 2x1000 square degrees, 11 Mpx) has observed ~20% 1-sigma Fermi error box (A. Goldstein, GCN 9056) with 1s exposure during all night: befoure, during and after GRB Time without time gap between images. Our unfiltered images are calibrated relative to Tycho stars (V). The magnitude limit of the each emage is ~9.1 m at the edge of FOW (some ising was attend at this night). We do not detect OT inside 20% part of the error box. We conclude (in the case that GRB inside our FOW ): 1). the optical fluence during the short 0.3 s GRBurst is limited by ~<= 3 x 10E-9 erg/cm_2 excluding possible host galaxy absorbtion. The event fluence (8-1000 keV) in this time interval is (9.61 +/- 0.31)E-07 erg/cm^2 (A. Goldstein, GCN 9056). So: 2). Optical-Fluence/Gamma-Fluence(8-1000 keV) ~ < 1/300 The same ratio for long GRB080319B is Optical-Fluence/Gamma-Fluence(8 - 1000 keV) ~ 1/140 (Naked Eye GRB, Racusin, Karpov et al., Nature, vol.455, 183, 2008). The film of our observations is available at http://observ.pereplet.ru/images/GRB090320B/GRB090328B.gif Black circles are the 1-sigma and 3-sigma error boxes (A. Goldstein, GCN 9056).

Marisaldi, on behalf of the AGILE MCAL team report: Konus-Wind, Konus-RF, Mars-Odyssey (GRS and HEND), and INTEGRAL-SPI-ACS observed the intense GRB 090408b (Golenetskii et al., GCN 9121). It was also observed by AGILE-MCAL and SuperAGILE (outside the coded field of view). We have triangulated it to the following 3-sigma error box: ----------------------------------------------- RA(2000), deg Dec(2000), deg ----------------------------------------------- Center: 43.98 (02h 55m 56s) +26.61 (+26d 36' 36") Corners: 43.95 (02h 55m 48s) +27.59 (+27d 35' 24") 42.98 (02h 51m 55s) +27.78 (+27d 46' 48") 44.05 (02h 56m 12s) +25.64 (+25d 38' 24") 44.97 (02h 59m 53s) +25.49 (+25d 29' 24") ----------------------------------------------- The error box area is 1.48 sq. deg. This error box may be improved. IPN triangulation map is avalable at at http://www.ioffe.ru/LEA/GRBs/GRB090408_T71198/IPN --
