On analysing the geometry causing this, I dismissed the '45 degrees' falsely (?) on these grounds: No value for the solar concentrator angles found They appeared closer to 60 then 45 45 degrees will cause sun-concentrator-panel beams to reflect to the other concentrator, then back towards the Sun, ie normal geoflare. 60 degrees will end up 60 degrees off. But there can/will be some angle near 60 that will end up 45 degrees off - probably (15*45+45*60)/60 = 56.25 /Björn ----- Original Message ----- From: "Ed Cannon" <edcannonsat@yahoo.com> To: "post seesat" <SeeSat-L@satobs.org> Sent: Wednesday, February 18, 2009 6:47 AM Subject: re: Thoughts on the Upcoming Geosat Flaring Season > Further follow-up on this thread.
