EUV observations of the solar corona with superhigh spatial resolution in the ARCA project

Abstract

Observing the Sun’s hot corona with sub-second spatial resolution is important in solving a number of basic solar physics problems. The new ARCA satellite observatory under development at the Lebedev Physical Institute, Russian Academy of Sciences, will be first to provide images of the hot solar corona with a spatial resolution of about 0.18 arcsec. Scientific and technical features of the observatory are discussed.
