The solar eclipse of July 1, 2011 was a very "small" partial eclipse. The earth was only touched by the penumbra of the moon over the sea between Antarctica and Africa . In South Africa itself nothing of this mini-eclipse could be seen, in which a maximum of only 3% of the solar disk was covered.

It was the last in a series of the semester cycle , the penultimate one of which was the solar eclipse on January 4, 2011 . Due to the solar eclipse on June 1, 2011 , the next series of the semester cycle had already started.

With the eclipse of July 1st, series number 156 of the so-called selection cycle Saros (short: the Saros cycle 156) began, which will include a total of 69 eclipses every 18.03 years. Its subsequent seven eclipses will also be partial , but the coverage will continue to increase until the umbra of the moon finally hits the earth. The ninth eclipse on September 26th, 2155 will then be the first of a total of 52 annular solar eclipses of Saros 156. At its end, another nine partial solar eclipses will follow by July 14, 3237.

The distance to the previous eclipse on June 1st was the shortest possible distance between two solar or lunar eclipses. Solar eclipses with a direct sequence of two new moons are the "ideal framework" for a lunar eclipse of high totality. One of these took place with a total of 100 minutes during the full moon between the two solar eclipses, ie on June 15, 2011. In Central Europe the moon rose already eclipsed, the totality was not fully observable here.

Remarks

  1. ↑ Annular solar eclipses are about as frequent as total solar eclipses. The frequent repetition of the same type of darkness is almost the trademark of the Saros cycle.
