Hello, I've read in one of the files that was included with the latest version of IRIDFLAR, that Iridium 20 produces, now predictable, flares. It also states that these flashes are to short to be noticed with the eye. Is that because the satellite is rapidly turning around it's axis? I would also like to know what the standard, not flashing, magnitude is. I have a 7x50 binoculars and a 114mm F/7.9 reflector. For all I know these instruments should be able to spot a satellite. Since Iridium 20 is passing quite close the the zenit in the mornings, I'm planning some observations to it. Many thanx in advance, Cees Bassa
