Iridium paroxysm
Résumé: flash Iridium double simultané, l'un des satellites dépassant la magnitude -8. POR Munich, 12 juin 2006 à 23h59.
Yesterday evening, a flare from Iridium 52 front antenna MMA0 was foreseen at POR Munich, in Virgo, -8 magnitude at 23:59:02 local time according to http://heavens-above.com and -6.5 mag according to http://calsky.com. The latter source indicated that Iridium 98, a spare satellite with unknown status, might flare (also from MMA0 front antenna) to -6.2 mag one second earlier (23:59:01), only 3.5° apart from the Iridium 52 flare, in Bootes.
Both flares went beyond expectations, the brightest one from Iridium 52 exceeding -8 mag, and the other one being almost as bright. It was the most spectacular Iridium event I ever saw.
