GCN Circular 21418
J. P. Norris (BSU), S. D. Barthelmy (GSFC), S. B. Cenko (GSFC), A. Y. Lien (GSFC/UMBC) report on behalf of the Swift-BAT team: We report the spectral lag analysis for GRB 170803A (LaPorte et al., GCN Circ. 21405) based on the BAT data. The lag analysis finds a lag of 43 (+12, -12) ms for the 100-350 keV to 25-50 keV band, and 76 (+40, -26) ms for the 50-100 keV to 15-25 keV band. These values are consistent with those of long GRBs.
