Tonight's full Moon is special. It coincides with the closest approach of our nearest celestial neighbour. The combination of the Moon's closeness (called Perigee) and it being at full illumination means that its brightness is increased by 30% and its apparent size in the sky will increase by around 14%.
Supermoons dont often happen, the last one being in March 2011 last year. There were no increase in earthquake or tectonic activity as predicted by some who suggested that Supermoons cause such events.
Lets hope its clear to witness this special event.
