TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2896 SUBJECT: Very high activity of SGR 1806-20 DATE: 04/12/22 16:57:06 GMT FROM: Dmitry Frederiks at Ioffe Institute S. Golenetskii, R.Aptekar, E. Mazets, V. Pal'shin, D. Frederiks and T. Cline on behalf of the Konus-Wind team, report: During 21 December more than 30 SGR-like bursts were detected by Konus-Wind and Helicon-Coronas-F with peak fluxes varied from 5e-7 to 8e-5 erg /cm2 s. The time interval between bursts varied from seconds to hours. The triangulation of several these bursts indicated that their origin is SGR 1806-20. This is the second series of bursts from this source. The previous one was detected on 5 October (GCN 2769). Now we have the data till 01:28 UT December 22. The last burst is seen at 00:50:52 s UT in the Helicon background data. Details on triangulation and the full list of bursts with their characteristics will be given later.
