Another possible source of flares (or clints) off the Iridium spacevehicle might be off two other surfaces of the spacevehicle that are coated with flexible optical solar reflector like the MMAs. Both surfaces are located on the main bus and on the plus X, the direction of the velocity vector (ram side?) of the SV. One equipment panel underneath the MMAs, it has about the same dimension as the MMS (86 x 188 cm) but is pretty well shielded by the MMAs as viewed from the ground. The other is the Battery Radiator Assembly (called the BRA by the Lockheed gang who designed it). It is about 78 x 84 cm, is located on the upper bus between the solar arrays and is somewhat "faceted". It might catch and reflect light under some illumination angles. Still both of the surfaces are located on lines which are along the earth radius line. Do either of these surface correlate to the sighting under investigation.
