TITLE:   GCN GRB OBSERVATION REPORT
NUMBER:  1391
SUBJECT: IPN triangulation of a burst from SGR1806-20
DATE:    02/05/16 00:18:36 GMT
FROM:    Kevin Hurley at UCBerkeley/SSL  <khurley@sunspot.ssl.berkeley.edu>

K. Hurley, on behalf of the Ulysses GRB team, and 

D. Smith, R. Lin, J. McTiernan, R. Schwartz, C. Wigger, W. Hajdas,
and A. Zehnder, on behalf of the RHESSI GRB team, report:

Ulysses and RHESSI observed a burst on May 15 at 01:26:41 UT with ~20
ms duration.  Triangulation gives an annulus which is consistent with
the position of SGR1806-20.  Ulysses has in addition observed numerous
short events over the past several days.  Although none could be
triangulated, this may suggest that SGR1806-20 is entering a new period
of activity.
