The John W. Evans Solar Facility consists of two main telescopes: a 16" coronagraph and a 12" coelostat telescope. Each of these telescopes can be used to feed one of several instruments. This means that two observing programs can be run simultaneously.
The Evans Facility is used to conduct observations of the sun for both local staff and visiting scientists worldwide. Observations are made of the solar corona, and also of transient phenomena such as flares, eruptive prominences, and surges, as well as quiet sun features.
