Abstract

The Large Angle Spectroscopic Coronagraph (LASCO) is a three coronagraph package which has been jointly developed for the Solar and Heliospheric Observatory (SOHO) mission by the Naval Research Laboratory (USA), the Laboratoire d'Astronomie Spatiale (France), the Max-Planck-Institut fur Aeronomie (Germany), and the University of Birmingham (UK). LASCO comprises three coronagraphs, C1, C2, and C3, that together imagethe solar corona from 1.1 to 30 R. (C1: 1.1 - 3 R., C2: 1.5 - 6 R., and C3: 3.7 - 30 R. ) The C1 coronagraph is a newly developed mirror version of the classic internally-occulted Lyot coronagraph, while the C2and C3 coronagraphs are externally occulted instruments. High-resolution imaging spectroscopy of the corona from 1.1 to 3 R. can be performed with the Fabry-Perot interferometer in C1. High-volume memories anda high-speed microprocessor enable extensive on-board image processing. Image compression by a factor of about 10 will result in the transmission of 10 full images per hour.
