A. von Kienlin (MPE) reports on behalf of the Fermi GBM Team:
"At 05:52:33.73 UT on 26 January 2009, the Fermi Gamma-Ray Burst Monitor
triggered and located GRB 090126C (trigger 254641955 / 090126245).
The on-ground calculated location, using the GBM trigger
data, is RA = 222.9, DEC = 39.2 (J2000 degrees,
equivalent to 14h 52m, 39d 12'), with an uncertainty
of 14.6 degrees (radius, 1-sigma containment,
statistical only; there is additionally a systematic
error which is currently estimated to be 2 to 3 degrees).
The angle from the Fermi LAT boresight is 68 degrees.
Since this GRB is weak and short (~ 1 sec), the time-averaged
spectrum is poorly constrained."
