(ISDC-Versoix) on behalf of the IBAS Localization Team and F.I.Mirabel
(SAp-Saclay) on behalf of the INTEGRAL Science Working Team report:
A strong increase in the activity of SGR 1806-20 has been detcted by IBAS
starting at 13:57 UT of October 5. The activity consists of an
approximately 6 min long, multipeaked outburst, followed by a few shorter
bursts.
During the peaks of the long outburst the counting rate in the IBIS/ISGRI
detector saturates the available telemetry.
Analysis is in progress to estimate the event fluence and spectrum.
Rapid observations at other wavelengths are encouraged.
