TITLE: GCN CIRCULAR NUMBER: 19044 SUBJECT: Swift trigger 674752 is likely due to a noise fluctuation DATE: 16/02/21 21:01:58 GMT FROM: Amy Lien at GSFC A. Y. Lien (GSFC/UMBC), S. D. Barthelmy (GSFC), D. Malesani (DARK/NBI) and K. L. Page (U Leicester) report on behalf of the Swift Team: We conclude that Swift trigger 674752 (Lien et al., GCN Circ. 19031) was likely the result of noise fluctuations. We have analyzed the BAT data set from T-239 to T+963 sec from the recent telemetry downlink. We find that there is no sign of significant emission from the trigger location at any point in this interval. But with a significance of 5.2 sigma, we can not rule out an astrophysical source. No XRT or UVOT data are available for this trigger.
