TITLE: GCN CIRCULAR NUMBER: 28192 SUBJECT: Konus-Wind detection of GRB 200729A DATE: 20/08/02 16:38:02 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 long GRB 200729A (Swift trigger #984929: Evans et al., GCN 28165, Krimm et al., GCN 28179; Fermi-GBM Sub-Threshold candidate: Malacaria et al., GCN 28174) was detected by Konus-Wind in the waiting mode. The burst light curve shows a single emission episode with a duration of ~ 74 s. The K-W light curve of this burst is available at http://www.ioffe.rssi.ru/LEA/GRBs/GRB200729A/ As observed by Konus-Wind, the burst had a fluence of 5.23(-1.00,+1.32)x10^-6 erg/cm2 and a 2.944-s peak flux, measured from ~T0(BAT)+5.8 s, of 2.18(-0.55,+0.66)x10^-7 erg/cm2/s (both in the 20 - 1500 keV energy range). The K-W 3-channel time-integrated spectrum (from ~T0(BAT) s to ~T0(BAT)+73.5 s) is well described by a cutoff power-law model with alpha = -0.47(-0.3,+0.5) and Ep = 269(-65,+105) keV. All the quoted errors are estimated at the 1 sigma confidence level. All the presented results are preliminary.
