UVCS - Ultraviolet Coronagraph Spectrometer
- Ray O'Neal
UVCS is a spectral coronagraph on SOHO which utilizes ultraviolet spectroscopy and visible polarimetry to study inner coronal plasma. Its range is between 2 and 10 solar radii, and is capable of determining the proton velocity distribution, electron temperature and density, and O VI, Si XII, and Mg X outflow velocities and temperatures. The UVCS synoptic data set consists of scans in both Lyman Alpha and Oxygen VI, from 1.5 to 3 solar radii, at 1216 Å and 1035 Å respectively. These are daily observations which take a total of 15 hours to complete.
