It is possible, though extremely rare, that part of the umbra intersects with Earth (thus creating an annular or total eclipse), but not its central line. This is then called a non-central total or annular eclipse. [17] Gamma is a measure of how centrally the shadow strikes. The last (umbral yet) non-central solar eclipse was on April 29, 2014 ...
This total solar eclipse had a maximum duration of 6 minutes and 38.86 seconds. The longest possible duration of a total solar eclipse is 7 minutes and 32 seconds. The longest annular solar eclipse of the 21st century took place on January 15, 2010, with a duration of 11 minutes and 7.8 seconds. The maximum possible duration is 12 minutes and ...
A total solar eclipse occurs when the Earth intersects the umbra portion of the Moon's shadow. When the umbra does not reach the surface of the Earth, the Sun is only partially occulted, resulting in an annular eclipse. Partial solar eclipses occur when the viewer is inside the penumbra. [14]
A total solar eclipse is far different from a partial eclipse or a ring of fire event, as the moon completely covers the sun, casting a shadow that plunges a swath of the Earth into darkness for ...
∎ Annular: This type of eclipse is the most commonly seen and is witnessed leading up to a total eclipse. When the moon passes directly between the Earth and the sun, an annual eclipse occurs.
A hybrid solar eclipse switches between annular and total. A partial solar eclipse happens when the moon only covers a portion of the sun. At least two solar eclipses happen each year, per NASA .
From 1900 to 2100, the District of Columbia will have recorded a total of 78 solar eclipses, of which none were or will be total or annular eclipses. The District of Columbia is the only territory of the United States, except for Puerto Rico and the U.S. Virgin Islands, to not experience an annular or total solar eclipse from 1900 to 2100.
Since the sun is never completely obscured, observers must wear proper eye protection at all times during this eclipse, according to NASA. Annular solar eclipses are different from total solar ...
