Stamatikos (NASA/ORAU) report on behalf of\nthe Swift Team:\n\nAt 20:45:10 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated the SGR 1806-20 (trigger=291587).  We note that the initial\nGCN Notice went out with a dual identification of this source (both\nSGR 1900+14 and SGR 1806-20).  This is due to a mismatch error\nin the catalog numbers used between the on-board and ground catalogs\nfor this source.  The real identification is SGR 1806-20.  We also\nnote that because of a star tracker loss-of-lock error, the flight\nposition is 10 arcmin off the true position. \nThe BAT light curve shows a large initial spike of ~190,000 counts/sec\nwith an ~2 sec FWZM, followed by 4 smaller spikes: ~2000 cnts/sec\nat ~T+3 sec, 10,000 cnts/sec at ~T+5 sec, 50,000 cnts/sec at ~T+14 sec,\nand 30,000 cnts/sec at ~T+18 sec. \n\nSwift-BAT, and other space instruments (e.g. Konus-WIND\nand Konus-A, Suzaku-WAM, IBAS, and SuperAGILE) have been\ndetecting elevated activity from this source over the\npast few days. \n\nNotably, earlier today (at 16:01:12 UT, Trigger #291566)\na 50,000 counts/second burst (250 times the flux of \nthe Crab) was detected by BAT,  which made it the \nthird largest SGR 'baby' burst (excluding activity \nrelated to the superburst) imaged by the Swift mission.  \nThe new Trigger #291587 burst reported here is much larger.",
