OTV-3 X-37B Sighting (Satellite)
It is now believed that it was not a fuel dump, but rather a retro (i.e. reverse) burn of both the Spaceplane and its accompanied 2nd stage rocket.
The retro burn for the 2nd stage was to de-orbit it. It is strange that OTV (Orbital Test Vehicle) also retro-fired at the same time and it is assumed it was to lower the orbit slightly.
