Cummings at Swift Jay Cummings reports on behalf of the Neil Gehrels Swift Observatory team Ground data analysis shows that Swift trigger 809374 (Cummings et al. GCN Circ # 22406) was an artifact due to incomplete subtraction of the nearby bright source Cyg-X1, and was not due to any new astrophysical source.
