![]() Subsequent increased surveillance of both local and deep space has turned up nothing of consequence. To this date there have been no further incursions. The so-called "Fireflies" were not detected upon approach: there was no indication of their presence prior to the simultaneous destruction of three communications satellites in geostationary orbit several seconds prior to atmospheric impact. We have found no fragments or samples of any kind. All objects appear to have disintegrated in the atmosphere. The objects contained high concentrations of iron, judging by subsequent mesospheric elevations of that element. Mean mass per object is thought to be on the order of 2-5 kg, based upon opportunistic visual/radar profiles and observed rates of atmospheric braking prior to burn-up. Objects emitted strong omnidirectional radio signals with primary emission peaks at 35m and 394m. ![]() Objects converged in a precise latitudinal/longitudinal grid all burned up within 45 - 72 seconds of contact with upper atmosphere. ![]() ![]() The "Firefall" Event: Executive Summary Time/Date:Ħ5,536 objects of unknown (presumably extraterrestrial) origin simultaneously hit atmosphere on, 1034:43. ![]()
