Today, Saturday, March 19, we experience one of those evenings that sky gazers have been anticipating for a long time. A rare lunar phenomenon is about to happen. You may not even notice it yourself if you are simply a casual observer but tonight the moon will appear larger and brighter than normal.
The moon has not been this close to the Earth for eighteen years. Some astrologists refer to this as a supermoon but there are even those who are calling tonight's moon an extreme supermoon because the moon will also be at the fullest part of its sequence. The real name for the term is rather different - astrological purists refer to it as a lunar perigee.
