Swift Trigger 1191994 is not an astrophysical event
Abstract
At 08:11:59 UT on 2023-09-14, the Swift Burst Alert Telescope (BAT) misidentified the location of a strong image peak due to a known race condition (the '7 minute problem') in the on-board software. The image peak was due to the source SWIFT J1727.8-1613, at levels consistent with other measurements in its current bright outburst and does not represent a sudden rate increase. (See https://swift.gsfc.nasa.gov/results/transients/weak/SWIFTJ1727.8-1613/ for current source intensity.)
