GCN Circular 15126
J. Norris (BSU), S. D. Barthelmy (GSFC), T. Sakamoto (AGU), N. Gehrels (GSFC) We report the spectral lag analysis for GRB 130822A (Kocevski, et al., GCN Circ. 15112) based on the BAT data. Using 1-ms binned light curve, the spectral lag for the 15-25 keV to 50-100 keV bands is 2.6 (+3.5/-3.2) ms. Since the lag value is consistent with zero, we believe this burst belongs to a short burst category. There is no evidence for extended emission.
