Yohkoh SXT Image Map

The Yohkoh Soft X-ray Telescope (SXT) the full solar disk (42 x 42 arcminutes)in the 0.25 - 4.0 keV range. It consists of a glancing incidence mirror and a CCD sensor and used thin metallic filters to acquire images in restricted portions of its energy range. SXT could resolve features down to 2.5 arcseconds. Information about the temperature and density of the plasma emitting the observed x-rays was obtained by comparing images acquired with the different filters. Images could be obtained every 2 to 8 seconds. Smaller images with a single filter could be obtained as frequently as once every 0.5 seconds.

Yohkoh was launched on 30 August 1991 and ceased operations on 14 December 2001.
