THE SECRET SPIES IN THE SKY - Imagery, Data Analysis, and Discussions relating to Military Space
SatTrackCam Leiden (Cospar 4353) is a satellite tracking station located at Leiden, the Netherlands. The tracking focus is on classified objects - i.e. "spy satellites". With a camera, accurate positional measurements on satellites of interest are obtained in order to determine their orbits. Orbital behaviour is analysed.
This blog analyses Missile tests too.

USA 116 keyhole flare
Last night at 1:06:25 UTC (3:06 am local time) I observed a nice mag. -2 flare of Keyhole USA 116 (1995-066A, #23728). The onset of the flare was captured by the camera, the image yielding two nice positions.
This was the first time I imaged USA 116. The obtained positions are on-track and at best some 0.1s early.
I also captured Lacrosse 4 (2000-047A), as I did a few nights earlier, on the 12th June. The June 12 data were "only"0.45s late relative to a 20-day old elset, and some 0.17 deg off-track in cross-track.
Last night's 2000-047A data are some 0.15s early, and again off track (about 0.12 deg. in cross-track) relative to an updated 3-day old elset (elset 06165.01332539).
