The mysterious Kosmos-2499 made another close pass near Briz-KM on November 25, 2014. The subsequent modeling of the pair's motion by Russian observers based on available orbital elements data indicated that Kosmos-2499 had come within 526 meters from Briz-KM at a relative speed of just 0.064 meters per second at 05:54 Moscow Time. The spacecraft spent most of the day maneuvering at a distance from a half a kilometer to one kilometer from its target.
After several days of orbiting the Earth at an average altitude from 20 to 30 meters below Briz-KM, Kosmos-2499 climbed few dozen of meters above the stage on November 29, 2014, estimates showed. A day later, to the surprise and delight of the amateur radio enthusiasts around the world, the mystery satellite started transmitting telemetry in Morse code under a call sign RS-47, a Russian amateur radio enthusiast Dmitry Pashkov reported. (Pashkov first detected mysterious signals that he had eventually traced to Kosmos-2499 in the summer of 2014.)
This radio-signature was typical of all satellites based on the Yubileiny platform -- another evidence of the similarity between Kosmos-2499 and its potential civilian cousins."
