re: Not anomalism...
Probably not, this was on the evenings of the millenium near year, local midnight, E. coast USA, from Dec 31/Jan1 and Jan1/Jan2 and the position was SW of Orion, where there is a stable geostationary orbit "sweet spot" (satellites placed here tend to be orbitally stable and require no maneuvering to remain on station). It was almost certainly a reflection from a geostationary satellite, although the magnitude (-1) contraindicates this. Another mystery.
