The term supermoon is used to describe a full or new moon that occurs when the moon is at or near perigee, its nearest position to the Earth. The astronomical term for this phenomenon is perigee-syzygy.
Supermoon Definition
The term “supermoon” was first coined in 1979 by astrologer Richard Nolle1 who defined a supermoon is a new or full moon that occurred within 90% of perigee. According to this definition, a supermoon happens about 3-5 times a year, some more impressive than others.
Nolle believed that this period was marked by “geophysical stress” caused by the increased influence of the moon and some astrologers will mark this time to be watchful for earthquakes, volcano eruptions, and severe weather patterns.
Supermoon in Magick
Many witches believe that the supermoon is the most opportune time to do any lunar magic of any sort. The energy of the sign that the moon happens to be traveling through at that time would also be greatly enhanced.
