- LASCO
-
- LASCO (Large Angle Spectroscopic Coronagraph) observes the outer solar atmosphere from near the solar limb to a
- distance of 21 million km, i.e. about one seventh of the distance between the Sun and the Earth. (The ground-based
- coronagraphs do not exceed a distance over 1.4 solar radii.)
-
- The essential questions of solar physics to be addressed by LASCO are:
- ∑ How is the corona heated?
- ∑ Where and how is the solar wind accelerated?
- ∑ What causes coronal mass ejections, and what role do they play
- in the evolutionary development of the large-scale magnetic
- field?
- ∑ What are the distribution and properties of the zodiacal dust
- cloud, and what are the effects on it of the small 'sungrazing'
- comets?
