Description

Sunspots are magnetic storms up to 8,000 miles in diameter. This photo was taken during a partial eclipse when the Sun was at a peak of activity. A special filter was attached to the telescope allowing only 1/10,000th of 1% of the light to pass through. Observing the sun through a telescope unfiltered can cause instant blindness. Even the viewfinder must be covered as a precaution. As seen from the Earth, a solar eclipse occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks ("occults") the Sun. This can happen only at new moon, when the Sun and the Moon are in conjunction as seen from Earth in an alignment referred to as syzygy. In a total eclipse, the disk of the Sun is fully obscured by the Moon.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 Earth's polar regions and never intersects Earth's surface.
