ARKA or MKA-PN 5 is a Russian microsatellite solar observatory.
ARKA features a pair of solar telescopes with super-high angular resolution reaching around 100 kilometers. One instrument would be developed in Russia by Lebedev Physics Institute, FIAN, IFM in Novgorod and IKI in Moscow. Another instrument could be supplied by an US institute.
ARKA was to be based on Lavochkin's Karat microsatellite bus, but was cancelled with the Karat program in March 2014.
