Subject
AXP 1E1547.0-5408: Fermi GBM detection of additional bursts
Date

From
Andreas von Kienlin at MPE <azk@mpe.mpg.de>
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.

List of all GBM triggers since the first trigger on 00:53:52.17 UT:
