You might check your logs against these two new bursts, and
against any of the other triggers listed in the accompanying
URL. Jerry Fishman of NASA would be very interested if our
SID observers detected a disturbance arising from any SGR/GRB.
In general, we would need two observers so that any event
is confirmed. Thanks, folks!

TITLE: GCN CIRCULAR
NUMBER: 9025
SUBJECT: SGR J1550-5418: two Fermi GBM triggers on March 22
DATE: 09/03/24 04:34:35 GMT
FROM: Alexander van der Horst at NASA/MSFC <Alexander.J.VanDerHorst at nasa.gov>
A.J. van der Horst (NASA/MSFC/ORAU) and C. Kouveliotou (NASA/MSFC)
report on behalf of the Fermi GBM team:
"The Fermi Gamma-Ray Burst Monitor (GBM) has triggered on two bursts from
SGR J1550-5418 on March 22. The first occurred at 18:56:23.75 (trigger
259440985 / 090322789) and the second at 22:39:15.75 UT (trigger 259454357
/ 090322944). The latter burst was very bright, and also detected by
SuperAGILE (GCN 9014). Both bursts were independently detected by INTEGRAL
SPI-ACS.
These are the first GBM triggers after the second active period of SGR
J1550-5418 that ended on February 24, 2009. A complete list of the GBM
triggers from this SGR can be found at:
