We report on a ~5th magnitude flash detected for approximately 10 minutes bytwo CONCAM all-sky cameras located in Cerro Pachon - Chile and La Palma -Spain. A third all-sky camera, located in Cerro Paranal - Chile did not detectthe flash, and therefore the authors of this paper suggest that the flash was aseries of cosmic-ray hits, meteors, or satellite glints. Another proposedhypothesis is that the flash was an astronomical transient with variableluminosity. In this paper we discuss bright optical transient detection usingfish-eye all-sky monitors, analyze the apparently false-positive opticaltransient, and propose possible causes to false optical transient detection inall-sky cameras.Comment: 7 figures, 3 tables, accepted PAS
