what are the effects of the solar eclips Eclipses may cause the temperature to decrease by 3 °C this causes the wind power to decrease potentially. In addition to the drop in light level and air temperature, animals change their behaviour during totality. when does this type of eclipse occur? A solar eclipse occurs when a portion of the Earth is engulfed in a shadow cast by the Moon which fully or partially blocks sunlight. This occurs when the Sun, Moon and Earth are aligned. can you tell me some of its types? UNANSWERABLE can you tell me one physical characteristic of the moon? It's surface is actually dark, although compared to the night sky it appears very bright, with a reflectance just slightly higher than that of worn asphalt. how is the atmosphere like here? It has an atmosphere so tenuous as to be nearly vacuum. Its sources include outgassing and sputtering, a product of the bombardment of lunar soil by solar wind ions. Elements that have been detected include sodium and potassium, helium, neon, argon and polonium. can you tell me any impact it has on us? UNANSWERABLE what path does the eclipse move on? During a central eclipse, the Moon's umbra (or antumbra, in the case of an annular eclipse) moves rapidly from west to east across the Earth. how long does this eclipse takes place? They are rare events. Although they occur somewhere on Earth every 18 months on average, it is estimated that they recur at any given place only once every 360 to 410 years, on average. what is the frequency of an eclipse per year? Between two and five solar eclipses occur every year, with at least one per eclipse season. how can one view the eclipse? It can be viewed only during the brief period of totality i.e. when the Sun's disk is completely covered. any precautions are needed to be taken while viewing it? The safest way to view the Sun's disk is by indirect projection. This can be done by projecting an image of the disk onto a white piece of paper or card using a pair of binoculars, a telescope, or another piece of cardboard with a small hole in it, often called a pinhole camera.

Solar eclipse [SEP] Partial and annular eclipses
Viewing the Sun during partial and annular eclipses (and during total eclipses outside the brief period of totality) requires special eye protection, or indirect viewing methods if eye damage is to be avoided. The Sun's disk can be viewed using appropriate filtration to block the harmful part of the Sun's radiation. Sunglasses do not make viewing the Sun safe. Only properly designed and certified solar filters should be used for direct viewing of the Sun's disk. Especially, self-made filters using common objects such as a floppy disk removed from its case, a Compact Disc, a black colour slide film, smoked glass, etc.
