Biltzinger, F. Kunzweiler, F. Berlato, J. Burgess & J. Greiner (all MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 605756501 at 01:41:36 on 13 March 2020 were automatically fitted for spectrum and sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427; Berlato et al. 2019, ApJ 873, 60).

Meegan (UAH) report on behalf of the Fermi GBM Team: "At 01:41:36.62 UT on 13 March 2020, the Fermi Gamma-Ray Burst Monitor (GBM) triggered and located GRB 200313A (trigger 605756501 / 200313071). The location for this GRB was reported in the Fermi GBM Final Real-time Localization GCN (GCN 27374). The GBM light curve shows a single broad peak with a duration (T90) of about 13.6 s (50-300 keV). The time-averaged spectrum from T0 s to T0+22.5 s is best fit by a Band function with Epeak = 279 +/- 10 keV, alpha = -0.64 +/- 0.02, and beta = -1.84 +/- 0.02. The event fluence (10-1000 keV) in this time interval is (7.37 +/- 0.05)E-05 erg/cm^2. The 1-sec peak photon flux measured starting from T0+2.4 s in the 10-1000 keV band is 57.0 +/- 0.7 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog: https://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html For Fermi GBM data and info, please visit the official Fermi GBM Support Page: https://fermi.gsfc.nasa.gov/ssc/data/access/gbm/"

Meegan, GCN Circ. 27383; BALROG localization: Biltzinger et al., GCN Circ. 27377) has been detected by Fermi (GBM trigger 605756501), Konus-Wind, INTEGRAL (SPI-ACS), and Mars-Odyssey (HEND), so far, at about 6097 s UT (01:41:37). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 73.028 (04h 52m 06s) +24.623 (+24d 37' 24") Corners: 73.480 (04h 53m 55s) +29.123 (+29d 07' 21") 73.078 (04h 52m 19s) +35.837 (+35d 50' 13") 72.077 (04h 48m 18s) +29.401 (+29d 24' 04") 72.972 (04h 51m 53s) +19.772 (+19d 46' 18") 74.907 (04h 59m 38s) +13.551 (+13d 33' 02") 74.212 (04h 56m 51s) +20.241 (+20d 14' 26") --------------------------------------------- The error box area is 18.9 sq. deg, and its maximum dimension is 22 deg (the minimum one is 1.2 deg). The Sun distance was 81 deg. This box may be improved. The localization is consistent with, but reduces the area of, the final Fermi-GBM (GCN Circ. 27374) and BALROG (GCN Circ. 27377) localizations. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB200313_T06098/IPN/ The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.

Aptekar, D. Frederiks, M. Ulanov, D. Svinkin, A. Tsvetkova, A. Lysenko, and T. Cline on behalf of the Konus-Wind team, report: The long-duration GRB 200313A (Fermi-GBM detection: The Fermi GBM team, GCN Circ. 27374; Lesage and C. Meegan, GCN Circ. 27383; BALROG localization: Biltzinger et al., GCN Circ. 27377; IPN triangulation: Hurley et al., GCN Circ. 27385) triggered Konus-Wind at T0=6098.088 s UT (01:41:38.088). The burst light curve shows a multipeaked structure which starts at ~T0-0.4 s and has a total duration of ~43 s. The emission is seen up to ~6 MeV. As observed by Konus-Wind, the burst had a fluence of 1.46(-0.14,+0.15)x10^-4 erg/cm2, and a 64-ms peak flux, measured from T0+2.528 s, of 3.42(-0.52,+0.53)x10^-5 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The time-averaged spectrum of the burst (measured from T0 to T0+45.824 s) is best fit in the 20 keV - 6 MeV range by the GRB (Band) model with the following parameters: the low-energy photon index alpha = -0.88(-0.10,+0.12), the high energy photon index beta = -2.07(-0.17,+0.12), the peak energy Ep = 442(-66,+77) keV (chi2 = 70/75 dof). The spectrum near the maximum count rate (measured from T0+2.048 to T0+3.072 s) is best fit in the 20 keV - 6 MeV range by the GRB (Band) model with the following parameters: the low-energy photon index alpha = -0.69(-0.13,+0.17), the high energy photon index beta = -2.24(-0.21,+0.16), the peak energy Ep = 424(-69,+70) keV (chi2 = 61/58 dof). The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB200313_T06098/ All the quoted errors are at the 90% confidence level. All the quoted values are preliminary.
