Title:
X-ray image of the sun
12 November 1991 This is an X-ray image of the sun taken 07:33 UT on 12 November 1991 and is described in the article "The Yohkoh Mission for High- Energy Solar Physics", by L. Acton, et. al., Science vol. 258 , 23 Oct. 1992 pp. 618-625. Three separate eposures of 9.5, 78, and 2668 milliseconds were combined in this image. Picture brightness scales as the logarithm of intensity. A thin aluminum filter restricted the instrument bandpass to the 3 to 40 Angstrom wavelength interval. The hot ionized gases in the solar atmosphere which emit in this interval, trace the solar magnetic fields etending up into the corona. Variations in brightness reflect variations in plasma temperature and density.
