A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking all or a portion of the Sun’s light. This celestial event creates a temporary shadow on Earth, casting darkness in the regions where the eclipse is visible. There are different types of solar eclipses, including total, partial, and annular eclipses, each characterized by the extent of the Sun’s coverage. Eclipses are awe-inspiring natural phenomena that captivate observers around the world, often sparking scientific curiosity and cultural significance.
*** WARNING ***
Before you start any solar observing program, make absolutely certain that you have safe filters and a safe set-up. Only use filters from reputable sources, and never use a “solar filter” that screws into an eyepiece. As Richard Hill states in Observe and Understand the Sun: “Observing the sun is the only inherently dangerous observing an amateur astronomer can do. Be aware of this at all times and take all necessary precautions. If you do not know a filter or procedure is safe then do not use it! Always err on the side of safety. An eye once damaged is forever damaged. Filters that let too much INFRARED light through can burn an eye if used visually. There is NO PAIN when this happens. Burned retinas can not be repaired. Excessive ULTRAVIOLET light has been shown to cause cataracts. So be very careful.”
