In light (so to speak) of the current interest in Iridium flares, I though it might be appropriate to call attention to a recent Russian paper which analyzes a 10-micron flare from one of the Lacrosse satellites to deduce the size and orientation of the reflecting surface, presumed to be the radar antenna. It's: "Nablyudeniye zerkal'nogo solnechnogo otrazheniya ot ISZ Lacross v spektral'nom diapazone 8-12 mkm" [Observation of a Specular Solar Reflection from a Lacrosse Satellite in the 8-12 Micron Band] by Ye. A. Grishin, S.N Melkov and V.L. Milovidov Kosmicheskiye Issledovaniya, 1997, Vol.35, No.4, pp. 353-355. I believe Kosmicheskiya Issledovaniya appears in an English translation, but I forget what it's called -- probably "Space Research."
