Kevin Fetter shared videos for two unknowns he observed earlier today.

His first unknown is USA 89 r [22519/92086C], last seen 60 days
ago. Propagating the 20 day old ISON elements forward and fitting for
mean anomaly, RA of ascending node and argument of perigee yields this
orbit. The drag term is a guess.

1 22519U 92086C   15120.06620370  .00000000  00000-0  10000-2 0    03
2 22519  56.8958 137.5305 3148984   7.7924  25.1880  8.94364049    03
# 20150430.07-20150430.07, 66 measurements, 0.006 deg rms

The second uknown appears to belong to the 2010-062 launch that
launched STPSat 2 [37222/10062A] as well as several other objects. Of
these we track STPSat 2 itself, STPSat 2 r [37228/10062G] and STPSat 2
HAPS [37229/10062H]. During the summer of 2013 we also briefly tracked
another object from this launch, which we labelled as
99207/10062X. This circular orbit fits Kevin's observations well.
