A total lunar eclipse will be visible from South Africa on the 15th of June 2011. The last total lunar eclipse visible from this region was in February 2008 and the next one will only be in September 2015.
A lunar eclipse occurs when the moon moves into the shadow of the Earth, where the Earth is then preventing the rays of the sun from striking the moon and thus making the moon appear dark. Though lunar eclipses happen at least twice a year, any given eclipse will only be visible from certain parts of the world. Furthermore total lunar eclipses are also rarer. So do make sure you grab the opportunity to have a look this June!
