pp. 795, 796: In Listing 21-11, the URLs for the realtime pictures of the Sun have changed. With the new URLs the example should read:

    Hydrogen Alpha Image of the Sun Desktop Component
  </TITLE>
  <ABSTRACT>
   This desktop component shows a picture of the Sun 
   as it appears this very minute from the top of 
   Sacramento Peak in New Mexico. The picture is taken 
   in a single color at the wavelength of the Hydrogen 
   alpha light (6563 Angstroms) using a monochrome 
   camera which produces a greyscale image in
   which the red light of Hydrogen alpha appears white.
