| 内容記述 | The Perseus Flasher (PF) is claimed to be an astrophysical source which frequently emits bright optical flashes (Katz et al. 1986). These flashes have all been detected by the naked eye, with the exception of one photographed flash for which an accurate position is measured. Notable properties of the PF are its large amplitude (greater than 19 mag), short duration (about 1 s), and frequent occurrence (a flash every 12 hr). Here, evidence is presented that the PF is not an astrophysical source but is merely the observation of glints of reflected sunlight from artificial earth satellites. This conclusion is supported by the following facts: (1) a total of 3400 hr of photographic, video, and CCD observations have detected no flashes in or near the small PF error box, despite the claim of one bright flash every 12 hr; (2) thirteen of the 26 flashes are shown to be nonastrophysical in origin; and (3) both the observational and theoretical glint rates indicate that most, if not all, PF observations are caused by satellite glints. |
