TLEs (Two-Line Elements) are available for this object, and for some of the other artsats on these pages.

The area/mass ratio is nominally -2.2 +/- 2.9 m²/kg (note that's a negative 2.2.) It's presumably very small (H=34.3), so I expect it's getting pushed around a bit by sunlight. But it looks as if it's not an ETBO.
