Dutch astronomer Marco Langbroek has photographed what he claims are the Soviet nuclear-powered satellites Kosmos-1860 and Kosmos-1412.
When posting their photos on his Twitter page, he referred to them as RORSAT (Radar Ocean Reconnaissance Satellites), an abbreviation that was used by Western countries when codenaming the Kosmos-1860 and the Kosmos 1412.
The photos, which were made in the Dutch town of Leiden, show what look like at least two bright points, seen against the background of stars in outer space.

These two images, which I shot from Leiden yesterday evening and this morning, show two old Soviet RORSAT, Kosmos 1860 and Kosmos 1412. These satellites were powered by a nuclear reactor.@MysteriousDrBex @drspacejunk @NuclearAnthro @SSC_NL pic.twitter.com/zfxnTrremK
Commenting on his tweet with the photos, Langbroek said that each of the alleged satellites was equipped with a BES-5 Buk on-board nuclear power unit with a capacity of 5 kilowatts.
The inclusion of a nuclear power unit was caused by a lack of energy from solar batteries used by the satellites' radar. For safety purposes, the satellites were taken out to the high orbit of Earth after the end of their service life.
