Circular_text TITLE: GCN CIRCULAR NUMBER: 10920 SUBJECT: GRB 100701B: Fermi GBM detection DATE: 10/07/02 08:50:29 GMT FROM: Suzanne Foley at MPE S. Foley (MPE) reports on behalf of the Fermi GBM Team: "At 11:45:23.07 UT on 01 July 2010, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 100701B (trigger 299677525 / 100701490). The on-ground calculated location, using the GBM trigger data, is RA = 45.49, DEC = -3.43 (J2000 degrees, equivalent to 03 h 02 m, -03 d 26 '), with an uncertainty of 1.0 degree (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 107 degrees. The GBM light curve consists of at least six main pulses with a duration (T90) of about 27.5 (+/-0.9) s (8-1000 keV). The time-averaged spectrum from T0-1.2 s to T0+32.7 s is well fit by a power law function with an exponential high energy cutoff. The power law index is -0.99 (+/-0.02) and the cutoff energy, parameterized as Epeak, is 1.85 (+/-0.16) MeV (CSTAT 695.8 for 360 d.o.f.). The event fluence (8-1000 keV) in this time interval is (2.86 +/- 0.03)E-05 erg/cm^2. The 1-sec peak photon flux measured starting from T0+3.4 s in the 8-1000 keV band is 22.6 +/- 0.3 ph/s/cm^2. A Band function fits the spectrum equally well (CSTAT 689.8 for 359 d.o.f.) with Epeak= 1.48 (+0.19/-0.17) MeV, alpha = -0.95 (+/-0.03) and beta = -2.47 (+0.18/-0.25) . The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

Tashiro, Y. Terada, T. Murakami, K. Makishima, and Y. Hanabata on behalf of the Suzaku-WAM team, report: The long bright GRB 100701B, seen by Fermi/GBM (Foley, GCN 10920), has also been detected by INTEGRAL (SPI-ACS), Suzaku (WAM), Konus-Wind, and MESSENGER (GRNS) so far. We have triangulated it to a 3 sigma error box whose coordinates are: ----------------------------------------------- RA(2000), deg Dec(2000), deg ----------------------------------------------- Center: 43.109 (02h 52m 26s) -2.224 (-02d 13' 25") Corners: 43.260 (02h 53m 02s) -2.497 (-02d 29' 49") 43.081 (02h 52m 19s) -2.310 (-02d 18' 36") 42.959 (02h 51m 50s) -1.947 (-01d 56' 50") 43.138 (02h 52m 33s) -2.137 (-02d 08' 14") ----------------------------------------------- The error box area is 149.7 sq. arcmin. This error box may be improved. The GBM position (Foley, GCN 10920) is 2.7 deg from the center of the box.

Circular_text TITLE: GCN CIRCULAR NUMBER: 10939 SUBJECT: Konus-Wind observation of GRB 100701B DATE: 10/07/06 08:05:36 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 bright hard GRB 100701B (localized by IPN, Golenetskii et al., GCN 10938) triggered Konus-Wind at T0=42319.075s UT (11:45:19.075) The burst light curve consists of several (>6) short hard pulses with a total duration of ~15 s. The emission is clearly seen up to 10 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB100701_T42319/ As observed by Konus-Wind the burst had a fluence of 5.0(+/-0.85)x10-5 erg/cm2, and a 256-ms peak flux measured from T0+3.584s of 2.2+/-0.3)x10-5 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The time-integrated spectrum of the burst (from T0 to T0+16.640 s) is best fit in the 20 keV - 10 MeV range by the GRB (Band) model, for which: the low-energy photon index alpha = -0.90 (+/-0.10), the high energy photon index beta = -2.7 ( <-2.1 ), the peak energy Ep = 1186(-243, +294)keV (chi2 = 74.4/84 dof). The spectrum at the maximum count rate (measured from T0+0.256 to T0+8.848 s) is best fit in the 20 keV - 10 MeV range by the GRB (Band) model, for which: the low-energy photon index alpha = -0.80 (+/-0.10), the high energy photon index beta = -2.6 ( <-2.2 ), the peak energy Ep = 1202(-217, +246)keV (chi2 = 90/84 dof). All the quoted results are preliminary. All the quoted errors are at the 90% confidence level.
