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.
