The Active Sun Telescope ArrayThe concept of the Active Sun Telescope Array (ASTA) designed as a part of the NASA Orbiting Solar Laboratory is described together with the details of the ASTA instrument package. The ASTA, which will investigate the phenomenology of the solar chromosphere and the corona, consists of six EUV/XUV solar telescopes designed to provide wide field solar images in narrow wavelength bands, high-resolution spectroheliograms, and line profiles of the solar plasma in the temperature range from 10,000 K to 30,000 K. The detectors used in the ASTA are of the multianode multichannel array photon-counting array detector type.
