Sunspots - cool areas on the surface of the sun
ON THE SURFACE OF THE SUN:
image of the sun was taken by simply projecting the sun's image
onto a sheet of paper using binoculars, in this case 20x80s,
mounted on a tripod. This is a safe and easy way to capture
this fascinating phenomenon on film. But remember, NEVER LOOK
AT THE SUN through binoculars, a telescope, or a camera with
a telephoto lens - you may cause yourself permanent blindness.
the image was formed and focused, I got in close using a 50mm
lens and took the above picture. You may, if you wish, make
a drawing of the sunspots which you see. The 11-year cycle of
the sun is climaxing in 2001, and sunspot activity like that
captured above can trigger solar eruptions which can send matter
to Earth and cause geomagnetic storms - Aurora

sunspots are currently visible, visit the website www.spaceweather.com.
Here is another interesting
website which includes a "history" section which
talks about ancient cultures and their understanding of sunspots.
