Good morning everybody! SOLAR WATCH FOR NOVEMBER 3, 2013: RARE HYBRID SOLAR ECLIPSE! A total solar eclipse will occur on November 3, 2013. Totality will be visible from the northern Atlantic Ocean (east of Florida) to Africa (Gabon (landfall), R. Congo, DR Congo, Uganda), with maximum of 1 minute and 39 seconds visible from the Atlantic Ocean south of Ivory Coast and Ghana. NB: PARTS OF SOUTH AFRICA WILL EXPERIENCE A PARTIAL ECLIPSE (UNFORTUNATELY!), JUST AFTER 16:OO WARNING: Be aware of the methods that should never be used for viewing a solar eclipse (or the Sun). Also be prepared to inform any other people youre responsible for to ensure their safety. Never look at eclipses through FOIL, binoculars, telescopes, any type of glasses, sunglasses, smoked glass, space blankets, CDs, polarizing filters, or exposed color film – none of these methods are strong enough to protect your eyes. Although the light wavelengths visible to the human eye are blocked by these objects, it is the non-visible light that causes damage to the eye; the ultraviolet and infrared wavelengths still get through, and cause just as much damage as the visible light. INSTRUCTIONS ON HOW TO MAKE YOUR OWN SAFE SOLAR ECLIPSE VIEWING APPARATUS WILL FOLLOW DURING THE DAY.... There are four types of solar eclipses: 1) A total eclipse occurs when the dark silhouette of the Moon completely obscures the intensely bright light of the Sun, allowing the much fainter solar corona to be visible. During any one eclipse, totality occurs at best only in a narrow track on the surface of Earth. 2) An annular eclipse occurs when the Sun and Moon are exactly in line, but the apparent size of the Moon is smaller than that of the Sun. Hence the Sun appears as a very bright ring, or annulus, surrounding the dark disk of the Moon. 3) A HYBRID ECLIPSE (also called annular/total eclipse) shifts between a total and annular eclipse. At certain points on the surface of Earth it appears as a total eclipse, whereas at other points it appears as annular. Hybrid eclipses are comparatively rare. 4) A partial eclipse occurs when the Sun and Moon are not exactly in line and the Moon only partially obscures the Sun. This phenomenon can usually be seen from a large part of Earth outside of the track of an annular or total eclipse. However, some eclipses can only be seen as a partial eclipse, because the umbra passes above the Earths polar regions and never intersects Earths surface.
