TITLE: GCN CIRCULAR NUMBER: 4310 SUBJECT: Possible resuming of the SGR 1806-20 activity DATE: 05/12/03 14:37:11 GMT FROM: Valentin Pal'shin at Ioffe Inst S. Golenetskii, R.Aptekar, E. Mazets, V. Pal'shin, D. Frederiks on behalf of Konus-Wind, and T. Cline on behalf of the Konus-Wind team, Two SGR-like events were detected recently by the Konus-Wind. The first one triggered the Konus-Wind on December 1 at 35965.468 s UT (09:59:25.468) . It had a duration ~3.6 sec, a fluence ~2.0x10^-5 erg/cm2, a peak flux ~1.2x10^-5 erg/cm2 s (both in 20-200 keV range). The time-integrated spectrum of the burst is well fit by the OTTB spectral model: dN/dE ~ E^{-1} exp(-E/kT) with kT = 19.7 � 0.6 keV, which is typical for SGR 1806-20. The second one occurred on December 3 at 32626.087 s UT (09:03:46.087) (only ~5 hours ago). It had an unusual long initial pulse with a duration ~9 sec followed by at least 9 weaker short bursts during the 229 sec of the Konus-Wind trigger record. So, this event can be classified as a burst series. The Konus-Wind spectral data for this event will be available in a day. The Konus ecliptic latitude response indicates that the source of these bursts is near the ecliptic plane. There were no solar flares at these times according to the GOES data. We suppose, that these events are originated from SGR 1806-20. But now we can not exclude the other possibilities. Further analysis using the data from other instruments will clarify this issue.
