Circular_text TITLE: GCN CIRCULAR NUMBER: 27386 SUBJECT: IPN triangulation of GRB 200313B (short) DATE: 20/03/15 17:21:19 GMT FROM: Dmitry Svinkin at Ioffe Institute D. Svinkin, S. Golenetskii, R. Aptekar, D. Frederiks, A. Ridnaia, and T. Cline on behalf of the Konus-Wind team, K. Hurley, on behalf of the IPN, and A. Goldstein, M. S. Briggs, and C. Wilson-Hodge on behalf of the Fermi GBM team, report: The short-duration GRB 200313B (Fermi-GBM detection: The Fermi GBM team, GCN Circ. 27379) has been detected by Fermi (GBM trigger 605789837) and Konus-Wind, so far, at about 39432 s UT (10:57:12). We have triangulated it to a Konus-GBM annulus centered at RA(2000)=154.610 deg (10h 18m 26s) Dec(2000)=+8.761 deg (+8d 45' 41"), whose radius is 60.602 +/- 2.419 deg (3 sigma). The IPN localization is consistent with, but reduces the area of, the Fermi-GBM one. This localization may be improved.

Circular_text TITLE: GCN CIRCULAR NUMBER: 27407 SUBJECT: Konus-Wind observation of GRB 200313B DATE: 20/03/18 13:30:13 GMT FROM: Anna Ridnaia at Ioffe Institute A. Ridnaia, S. Golenetskii, R. Aptekar, D. Frederiks, M. Ulanov, D. Svinkin, A. Tsvetkova, A. Lysenko, and T. Cline on behalf of the Konus-Wind team, report: The short-duration GRB 200313B (Fermi-GBM detection: The Fermi GBM team, GCN Circ. 27379; IPN triangulation: Svinkin et al., GCN Circ. 27386) triggered Konus-Wind at T0=39435.021 s UT (10:57:15.021). The burst light curve shows a single pulse which starts at ~T0-0.5 s and has a total duration of ~1.4 s. The emission is seen up to ~1 MeV. As observed by Konus-Wind, the burst had a fluence of 6.83(-2.07,+3.49)x10^-7 erg/cm2, and a 16-ms peak flux, measured from T0-0.016 s, of 1.90(-1.18,+1.53)x10^-6 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The time-averaged spectrum of the burst (measured from T0 to T0+0.256 s) is best fit in the 20 keV - 1 MeV range by a power law with exponential cutoff model: dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep) with alpha = -0.71(-0.91,+1.65) and Ep = 145(-55,+252) keV (chi2 = 31/26 dof). Fitting by a GRB (Band) model yields the same alpha and Ep, and an upper limit on the high energy photon index: beta < -1.8 (chi2 = 31/25 dof). The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB200313_T39435/ All the quoted errors are at the 90% confidence level. All the quoted values are preliminary.
