TITLE: GCN CIRCULAR NUMBER: 12512 SUBJECT: GRB 111026A: spectral lag value inconclusive for a short burst DATE: 11/10/30 18:13:02 GMT FROM: Scott Barthelmy at NASA/GSFC S. D. Barthelmy (GSFC), J. Norris (BSU), N. Gehrels (GSFC): We report the spectral lag analysis for GRB 111026A (GCN Circ. 12497) based on the BAT data. Using 64 ms binned light curves, the spectral lag for 15-25 keV to 50-100 keV is 27 +32/-40 msec. This value is not very constraining towards the shortness of this burst. And further, the fact that the burst is longer in the 15-25 keV band than in the higher energy band argues for a long burst assignment.
