The coordinates of the error box center: R.A. = 07h 18m 14s Dec = +17d 19' 12" The first image was at 2008-11-10 21:07:58.2 UT, 6 hours 42 min after the GRB time. The last image was at 2006-04-26 23:13:31.00 UT, 8 hours 48 min after the GRB time. We have 89 images with limit for coadded one up to 19m (S/N = 4). The unfiltered image is calibrated relative to USNO B1.0 (0.8 R + 0.2 B). This message can be cited.

The on-ground calculated location, using the GBM trigger data, is RA = 123.6, DEC = +21.2 (J2000 degrees, equivalent to 08h 14 m, 21 d 12'), with an uncertainty of 1 degree (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 67 degrees. The burst has a duration (T90) of about 20 s (8-1000 keV). The GBM light curve consists of three pulses, a bright FRED-like pulse from T0 to T0+5 s, a second weaker pulse at T0+9 s followed by weaker emission out to about T0+20 s. This is a hard gamma-ray burst with events detected up to about 2 MeV. Spectral analysis is on-going. The final results will be published in the GBM GRB Catalog."
