Summary

The Sun is a star, a hot, glowing, ball of gas at the center of our solar system. Without it, there would be no life on Earth. This presentation will review the overall properties of the Sun, its composition, its structural zones, its magnetic field, and its solar cycles. Man has known about the existence of features on the Sun since about 800 BC but it has only been within the last 100 years that astronomers have had the tools available to begin the exploration of it in detail.  Some of the telescopes and filters that enable us to view the sun safely will shown. Solar features visible in those instruments such sunspots, prominences, filaments, plages, and flares will be discussed.

This month's meeting will be "show and tell".  Bring in your eyepiece, scope, camera, or gadget you've bought recently and tell us about. If you've built some new gadget or developed an interesting software program then show and describe it to us. If you've had some successes or failures with some astronomy software or imaging processing technique, we'd love to hear about that as well!  You could even show us a few pictures of a recent trip to an observatory, astronomy museum, or space facility.
