On 18.11.2000, Iridium 8 had a -2 mag flare at 17:38:56, followed by Iridium 51, -6 mag at 17:40:13 UT. The exposure was taken from 17:38:45 to 17:40:25 in order to include both flares. Weather was partly cloudy; Iridium 51 illuminated a cloud; the stars of Per are seen to the lower right, some of them appear double since they were occulted by a cloud during the exposure.

The upper trail was caused by Mir, travelling from Oph to Sct on 18.11.2000 from 17:04:50 to 17:05:20 UT, brightness +2 mag. A blinking aircraft and several contrails are seen towards the horizon. This is typical in a region with heavy aircraft traffic (100 km from Brussels airport).

The bright trail was caused by Mir. The interrupted trail from botton center to the upper right corner came from the spent Soyuz rocket booster. This rocket booster is of cylindrical shape, and tumbles on its orbit around the Earth. Due to the tumbling, the different sides of the booster cause variations in brightness. Thus the booster flashes about every 2-3 seconds.

26.10.2001, ST8, exp. 2x10 min with Maksutov 900mm


Asteroid 1999KW4 is an Earth-orbit crosser of the Aten group (having its orbit mainly within the Earth's orbit), and came to a very close approach (0.03 AU, 4 mio. kms) in May 2001. The picture is a composite of 16 individual images taken on 26.5.2001 and show the asteroid's trail within about 3 hours. The bright star above is 61 Serpentis. The asteroid 1999KW4 had abrightness of about 11 mag.
