This java applet lets you explore the sun using different
frequencies of light: white (visible) light, x-ray, h-alpha, and
extreme ultraviolet. You can also explore a magnetogram, which shows
you the direction of the magnetic fields near the solar surface.
The full disk image of the sun that you can see on the right is
a white-light, or visible light image. Click on the buttons below
it to select one of the filters, then drag the filter box around
the sun to examine different parts of the solar disk.
You must use version 4.06 or later of Netscape Navigator
or version 4.0 or later Internet Explorer to view this applet.
This applet also includes several images, so it will take some time
to download over a modem. The applet will begin working before all
the images are downloaded, so don't let that confuse you!
