The flare limits now are about 76.7 N and 89.7 South Lat's. I'm guessing these will move North until Solstice. Must be rules based on the Sun's position. No such limits on daylight flares. Check out those for your South Pole. Could see more daylight flares in one day than all I have ever seen." ++++++++++++++ I didn't think of the fact that the darkness would eventually shade the satellites so that they would not flare. I do find it fascinating that beginning on 4/27 they get steadily brighter for 4 days than for 4 days they get steadily dimmer. See: http://www.heavens-above.com/iridium.asp?lat=-90&lng=0&alt=0&loc=Amundsen&TZ=NZST&Date=38468.1516666667&Dur=7 I do not understand how "daytime flares" could be seen right now at the S pole?!! I have not looked to see what the times of "daylight" are listed as being. See: http://www.heavens-above.com/iridiumdaytime.asp?lat=-90&lng=0&alt=0&loc=Amundsen&TZ=NZST&Date=38468.1129976852&Dur=7 Again they get steadily brighter then dimmer. I see that there is a gap beginning with the last flare listed like: 18 Apr 04:10:25 -0 52° 186° (S ) 37.7 km (W) -8 Iridium 16 and the next flare listed like: 27 Apr 11:16:28 -0 55° 16° (NNE) 41.1 km (W) -8 Iridium 72 Interesting stuff. It would be great if someone would do a prediction with iridiflare and see it matches with H-A.
