The LASCO instrument is a set of three coronagraphs
that image the solar corona from 1.1 to 32 solar radii. It is convenient to
measure distances in terms of solar radii. One solar radius is
about 700,000 km, 420,000 miles or 16 arc minutes. A coronagraph is a
telescope that is designed to block light coming from the solar disk, in order
to see the extremely faint emission from the region around the sun, called the corona.
The essential questions of solar physics to be addressed by LASCO are:
The LASCO experiment is investigating the following:
LASCO was built by a consortium of four US and European institutions:
MPS was responsible for the C1 coronagraph, which images the corona from 1.1 to 3 solar radii. It was also responsible for the door mechanisms and focus mechanisms for all the telescopes.
