Of course,this Elektro-L picture was recorded on September 22nd,at the northern hemisphere's autumnal equinox. For a moment on that date,the Sun was behind the geostationary satellite and a telltale glint of reflected sunlight is seen crossing the equator,at the location on the planet with satellite and sun directly overhead (5MB animated gif).
