T. M. Parsotan (GSFC) report on behalf of the Neil Gehrels Swift Observatory Team:
Using the data set from T-60 to T+243 sec from the recent telemetry downlink, we report further analysis of BAT trigger #1434591 (Parsotan et al GCN Circ. 43359). This trigger is due to noise, with no significant emission detected in the mask-weighted light curve or in the reconstructed image. No confirmed counterpart is found in the XRT or UVOT data within the BAT error circle, indicating that the trigger is not a real astrophysical event.
