Solar Images provide a history of what the Sun looked like in the past. Many solar features, like sunspot active regions, are reduced into tabular data for solar cycle activity indices. The images themselves give much more detail about how the regions looked and evolved -- an image is worth a thousand words. The different wavelengths provide information about processes going on at different levels of the solar atmosphere. The visible solar disk or photosphere has temperatures around 6000 degrees Kelvin. The temperature increases to 10 million degrees K in the high corona. Solar X-ray images showing the hottest features on the sun's disk are imaged in the high solar corona. White light images of sunspots are imaged on the sun's surface at 6000 degrees. Calcium and H-alpha images show chromospheric temperatures, lying just above the photosphere.
