R. Gupta (NASA GSFC), N. J. Klingler (GSFC/UMBC/CRESSTII), D. M. Palmer (LANL), 
and T. Sbarrato (INAF-OAB) report on behalf of the Neil Gehrels 
Swift Observatory Team:

Using the data set from T-183 to T+963 sec from telemetry downlinks,
we report further analysis of BAT trigger #1404295 (Klingler, et al.,
GCN Circ. 42290). This trigger is due to noise in the BAT image domain, 
with no significant emission detected in the mask-weighted light curve. 
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.
