"NOT MY VIDEO POSTED BY lUCKYMAURO"
Incredible photos are posted in the web by someone who claims that they maybe spaceships approaching our planet.
During spacewalks debris, both small and large, are often thrown off the station for convenience, although sometimes tools unintentionally slip away. Such was the case in December 1998 when a slidewire carrier and a worksite interface were lost by the STS-88 crew while conducting an extravehicular activity (EVA) for ISS. These objects were large enough to be tracked by the U.S. SSN and were cataloged (U.S. satellite numbers 25564 and 25565). Three other objects were also released by STS-88 spacewalkers, one inadvertently (an insulation blanket) and two by design (antenna spools), although only the former was officially cataloged (Debris, 1999).

I think this may be the insulation blanket.
