Setup: Watec 902H2 video, 50mm F/1.8, NTP, fixed setup
IOD format: http://www.satobs.org/position/IODformat.html
COSPAR 4171: 52.8344N, 6.3785E, 10m (WGS84)

NOTES:
======
1) The unknown appeared just after IGS 9 [40381/15004A]. It is very
   likely that this is the same object that Leo saw yesterday, either
   the IGS 10 payload or the rocket. Fitting a circular orbit yields:

1 99467U 17586A   17087.86027781  .00000000  00000-0  50000-4 0    06
2 99467  97.3143 160.2490 0001000   0.0000  58.9078 15.24496661    08
# 20170327.88-20170328.86, 12 measurements, 0.012 deg rms

   Since the object was not varying, and since the mean motion is near
   15.25 revs/day, I consider it likely that this is the payload; IGS
   10 [42072/17015A]
