TITLE: GCN CIRCULAR NUMBER: 31497 SUBJECT: Konus-Wind observation of the recent SGR 1935+2154 activity DATE: 22/01/19 13:46:08 GMT FROM: Anna Ridnaia at Ioffe Institute A. Ridnaia, D. Frederiks, M. Ulanov, D. Svinkin, A. Tsvetkova, A. Lysenko, and T. Cline on behalf of the Konus-Wind team, report: Since the last KW GCN on the ongoing SGR 1935+2154 activity (Ridnaia et al., GCN 31325) the instrument triggered on thirteen bright bursts from the source. The following is a list of the Konus-Wind triggers. --------------------------------------------- # Date T0(KW) s UT --------------------------------------------- 1 20211229 60082.391 s UT (16:41:22.391) 2 20220111 61551.690 s UT (17:05:51.690) 3 20220112 31161.806 s UT (08:39:21.806) 4 20220113 29375.444 s UT (08:09:35.444) 5 20220113 46378.912 s UT (12:52:58.912) 6 20220113 80750.270 s UT (22:25:50.270) 7 20220114 33622.126 s UT (09:20:22.126) 8 20220114 58119.186 s UT (16:08:39.186) 9 20220114 71808.322 s UT (19:56:48.322) 10 20220115 30352.115 s UT (08:25:52.115) 11 20220115 62515.176 s UT (17:21:55.176) 12 20220115 70649.225 s UT (19:37:29.225) 13 20220116 50974.968 s UT (14:09:34.968) --------------------------------------------- The bursts have durations (~0.2-0.9 s), energy fluences (0.9-5.9)x10^-6 erg/cm2, and spectral hardness (Ep ~ 20-45 keV) typical of bright short bursts from SGR 1935+2154 observed by KW previously. The detailed analysis of these bursts will be presented in the dedicated paper.
