GCN Circular 2311
S. Golenetskii, R.Aptekar, E. Mazets, V. Pal'shin, D. Frederiks (all Ioffe Institute), T. Cline (NASA GSFC), and K.Hurley (UCB) on behalf of the Konus-Wind team, report: A short soft burst was detected on 030719 by Konus-Wind starting at 83914.490s UT. The event had a duration of 0.25s, a soft energy spectrum ~ E^(-1)exp(-E/Eo) with Eo = 18.5 +/- 1 keV, fluence of 5x10-6 erg sm-2 and peak flux of 3x10-5 erg cm-2 s-1, evaluated both in 15-300 keV range. Apparently the burst originates from the SGR1806-20 or from its close vicinity in accordance with observations of the burst activity reported in GCN 2306, 2307, and 2308. Two weak soft events were detected by Konus-Wind in the background mode on 030720 at 08:07:12 and 22:34:19. The last event was detected by HETE (H2773). Estimated time delay is consistent with SGR1806-20 position.
