Dutch meteor observer Peter van Leuteren contacted me this week as he had a strange bright stationary object on images of his photographic all-sky meteor fireball camera, appearing in Ophiuchus at around 22:18 UTC on 3 consecutive nights. The same object was also noted visually, at mag. about +2.5, by BWGS chairman Bram Dorreman. It was evidently a brightly flaring geosynchonous satellite.
After an alert on Dutch and Belgian astronomy mailing lists, several observers noted it as well.
I took images last night (22 May, 22:13 - 22:25 UTC) in hopes of catching it and identifying it from the position. I used the Canon 450D with the EF 50/2.5 Macro for that purpose.
Unfortunately, as it later turned out, "the" mystery geosat (for now) was hidden just behind some tree branches for me. A few degrees west of it, I however captured a second flaring geosat!
That one has now been identified by Bram and me, based on my photographic positions, as Milstar 5 (2001-001A, #27168). I have made a movie out of 13 images (10 second exposures) spaced one minute each. It can be seen here (1.4 Mb animated GIF)
The FOV of the movie is a small crop from the images, at full pixel level. The object is moving southwards at about 55"/minute.
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.
