TITLE: GCN CIRCULAR NUMBER: 15853 SUBJECT: Konus-Wind observation of GRB 140215A DATE: 14/02/17 15:10:00 GMT FROM: Dmitry Frederiks at Ioffe Institute S. Golenetskii, R.Aptekar, D. Frederiks, V. Pal'shin, P. Oleynik, M. Ulanov, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, report: The long-duration GRB 140215A (Swift-BAT trigger 586680: Markwardt et al., GCN 15837; Barthelmy et al., GCN 15847) triggered Konus-Wind at T0=14831.638 s UT (04:07:11.638). The burst light curve shows a multi-peaked with a total duration of ~15 s. The emission is seen up to ~10 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB140215_T14831/ As observed by Konus-Wind, the burst had a fluence of (1.84 ± 0.15)x10-5 erg/cm2, and a 64-ms peak flux, measured from T0+4.800 s, of (3.57 ± 0.35)x10-6 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The time-averaged spectrum (measured from T0 to T0+15.360 s) is best fit in the 28 keV - 15 MeV range by the GRB (Band) function with the following model parameters: the low-energy photon index alpha = -0.66 ± 0.11, the high energy photon index beta = -2.94 ± 0.35, the peak energy Ep = 214 ± 14 keV, chi2 = 106/95 dof. The spectrum near the maximum count rate (measured from T0 to T0+7.168 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 = -0.46 ± 0.12, the high energy photon index beta = -2.83 ± 0.26, the peak energy Ep = 212 ± 14 keV, chi2 = 92.9/96 dof. All the quoted values are preliminary.
