At 00:17:11.870 UTC on March 28, 2010, CASTOR detected the 3,200th satellite since it began keeping a detailed catalogue on January 1, 2007.

The satellite was a Russian SL-8 rocket body launched on May 7, 1981 to place the Russian military telecommunications payload Cosmos 1269 into Low Earth Orbit (LEO). Cosmos 1269 is already listed in the CASTOR Satellite Catalogue as #1882. The satellite was 792 km in altitude and nearly directly above the CASTOR detector.

This is the 235th SL-8 (AKA R-14) type rocket body detected by CASTOR since January 1, 2007. At the present time there are approximately 300 SL-8 rocket bodies in orbit. CASTOR has detected approximately 79% of these objects and it is doubtful that this will be the last one CASTOR will detect.

CASTOR resumed its satellite surveys at the beginning of March 2010. In March, it detected an additional 50 satellites to add to the 3,153 satellites detected from 2007 to 2009.
