The Activity of the Soft Gamma Repeater SGR~1900+14 in 1998 from Konus-Wind Observations: 1. Short Recurrent Bursts

Results are presented of the observations of the soft gamma repeater SGR 1900+14 made on the Wind spacecraft during the source reactivation period from May 1998 to January 1999. Individual characteristics of recurrent bursts, such as their time histories, energy spectra, and maximum and integrated energy fluxes, are considered. Some statistical distributions and relationships are also presented. The close similarity of these events to the recurrent bursts observed from other SGRs argues for a common emission mechanism.

Activity of the Soft Gamma Repeater SGR 1900+14 in 1998 from Konus-Wind Observations: 2. The Giant August 27 Outburst

The results of observations of the giant 1998 August 27 outburst in SGR 1900+14 are presented. A comparison is made of the two extremely intense events on August 27, 1998 and March 5, 1979. The striking similarity between the outbursts strongly implies a common nature. The observation of two giant outbursts within 20 years from different sources suggests that such events occur in an SGR once every 50-100 years.
