Title: Solar corona/prominence seen through the White Light Coronograph
Description:
The solar corona and a solar prominence as seen through the White Light 
Coronograph, Skylab Experiment S052, on January 17, 1974. This view was 
reproduced from a television transmission made by a TV camera aboard the 
Skylab space station in Earth orbit. The bright spot is a burn in the 
vidicon. The solar corona is the halo around the Sun which is normally 
visible only at the time of solar eclipse by the Moon. The Skylab 
coronography uses an externally-mounted disk system which occults the 
brilliant solar surface while allowing the fainter radiation of the corona
to  enter an annulus and be photographed. A mirror system allows either TV 
viewing of the corona or photographic recording of the image.
