A. von Kienlin (MPE) and V. Connaughton (UAH)
report on behalf of the Fermi GBM Team:
"Since the first 18 triggers from AXP 1E1547.0-5408 detected
by the Fermi Gamma-ray Burst Monitor on 22 January 2009
(GCN 8835, Connaughton & Briggs), there have been 13 additional
triggers of Fermi GBM from this source.
The GBM on-board locations are all consistent with
the AXP 1E1547.0-5408 position. So there are a total of
31 triggered bursts from this source. Many other bursts
were recorded during times where GBM was still in trigger mode.
