SOHO Ultraviolet Coronagraph Spectrometer UVCS
UVCS Scientific Purpose
The purpose of the UVCS is to provide a detailed description of the
extended solar corona that can be used to address a broad range of scientific
questions regarding the nature of the solar corona and the generation of
the solar wind.
UVCS makes measurements of the solar corona between 2 and 10 solar radii from
sun center with high spectral and spatial resolution.
From the spectroscopic measurements at ultraviolet wavelengths, the
can be determined.
Information about the
- proton velocity distribution,
- proton outflow velocity,
- electron temperature, and
- O VI, Si XII, and Mg X outflow velocities and densities
can also be learned.
- O VI, Si XII, and Mg X velocity distributions,
- electron density, and
- minor ions densities
PRESS RELEASE SOHO's First Anniversary Press Release.
UVCS images and images from other SOHO instruments are available.
A smaller Spartan
UVCS has successfully observed the solar corona during
three Space Shuttle missions.
