This weekend we will see the moon at its closest point to Earth for 2012. This perigee-full moon is also considered a ‘SuperMoon’, a term coined by astrologer Richard Nolle. Whilst this is not the one of the extreme supermoons in the 21st century, it is still one of the many supermoons occurrences. By definition, a SuperMoon is a perigee-syzygy, a new or full moon (syzygy) which occurs when the Moon is at 90% or greater of its mean closest approach to Earth (perigee). An extreme SuperMoon is when the moon is at 100% or greater than 100% of its mean perigee.

The moon reaches its closest distance to Earth (perigee) at about 03.34 AM GMT on May 6 and two minutes later, syzygy occurs at 3.36AM GMT. At perigee, the moon will only be 356953 km from Earth, the closest for this year. Unfortunately for us in Malaysia, the full perigee-syzygy will occur during daylight (11.36 AM on Sunday 6 May). However, the moon would already look somewhat bigger a day before and after the perigee syzygy, and this is especially noticeable when the moon is close to the horizon at moonrise and moonset.
