ocr: LASCO Itis convenient to measure distances in terms of solar radii. One solar radius is about 700,000 km, or 420,000 miles, or 16 arc minutes. A coronagraph is a telescope that is designed to block light coming directly from the solar disk, in order to - see the ex- tremely faint emission from the region around the sun, called the corona.
