SVO Filter Profile Service

SOHO :SOHO, the Solar & Heliospheric Observatory, is a project of international collaboration between ESA and NASA to study the Sun from its deep core to the outer corona and the solar wind.
SOHO/LASCO :The Large Angle and Spectrometric Coronagraph Experiment (LASCO) is a set of three coronagraph telescopes that will record white light images of the solar corona from 1.1 through 30 solar radii. It also will record spectral images of the solar corona from 1.1 to 3.0 solar radii.id:SOHO/LASCO.a
