For those who have never seen one, an Iridium flare is one of the greatest manmade phenomena ever--albeit probably completely unintentional. The Iridium are a group of satellites that happen to have extremely reflective aluminum antenna coated with Teflon. During certain points in these satellites' orbits, the observer-satellite-Sun angle causes a large amount of light to shine down to the viewer for a period of seconds. It is truly an incredible experience. I've seen several.

Sadly, the replacement satellites will not "flare" like the ones they are replacing. The old Iridiums only have a few months left. A lecture entitled "The Final Flares" will explain how to search for these remaining predicted events with family and friends. The lecture will be at HRPO on Friday 23 December at 7:30pm. The talk is for a general adult audience and has no admission fee.
