Getting it in 20x120 binoculars, it was seen to be moving slowly eastward against the sky background. After a break to photograph a satellite with the Hewitt camera I returned to scan eastwards in the hope of finding the object again, but found it was still centered in the binoculars, although it had faded a few magnitudes. I'm not sure if the identity of this geostationary satellite was ever determined with certainty, but the initial sighting was just as it exited eclipse on a date when the Sun was at the same declination as the satellite. Any flat surface facing towards the Earth will produce a specular reflection under that geometry. SEDS and TSS were spectacular, but I'm happy they are short lived.
Space junk can ruin a lot of astronomical work.
