I watched 3 Iridium flares tonight in the mosquito laden air. One was a -8, the other 2, -6 apiece. The magnitudes seemed accurate even down to the 13 degrees altitude of the lowest one. It was a -6, was NNE and latest quite a bit longer than the others. Two questions: (1) Does H-A consider atmospheric extinction when making their flare magnitude predictions? (2) Does anyone know the lowest in the sky someone has observed an Iridium flare?
