An Iridium Flare is a reflection of the sun as it strikes the antenna of an Iridium system's satellite. When you are in the right location the flash can have an intensity of (-8)-- the number is from the web page and I'm not sure if has the same value as used in Astronomy. I have seen a few flares and they can be impressive--kids think they're cool.Check out the following web page for more information and other very relevant Astronomical information.http://www.heavens-above.com/The following is a good place to get the Lat/Long coordinate information for your location. 'Click" on your location (on the map) after you have accessed the map and the Lat/Long coordinates will be shown on the bottom of the map(noted "Center"). The negative sign is correct for the USA. (The link "Map showing geographical distribution of visitors" at the bottom of the Haven's Above web page shows the incorrect entry of USA visitors showing up as visitors in Asia!)http://MapsOnUs.switchboard.com/bin/maps-map/refsrc=SB.home/usr=~newSome Tips:(1) The information on your location can be saved (Bookmarked/Favorite) for your location for subsequent access.(2) There is an option (for Iridium Flare) to click on the Time and a sketch is shown. The sketch is "Only a Cartoon". Use the values of the Table to determine where to look.
