The term gives preference to the geometric alignment of Sun-Earth-Moon and allows the occurrence of perigee into a wider time period than the actual instant of perigee (up to about two weeks, which is nearly half of the Moon's orbit).
February's full moon is known as the "snow moon" because of the heavy snowfall that often occurs at that time of year, according to the Old Farmer's Almanac. The event will officially occur in the morning, but when the moon crosses the night sky - it will be brighter than it will at any point of the year, or even until 2026, according to Forbes.
The Almanac also states that other common names for February's full moon included the Hunger Moon, Bony Moon, and Little Famine Moon, because the harsh temperatures and poor climate made hunting hard.
Rao writes that most people won't be able to discern any apparent change in size or brightness of Tuesday's moon.
"This perceived increase in size happens whenever you see the moon, regardless of its phase, near the horizon".
The super snow moon is the second of three super moon's this year. The term went viral in March 2011 when some incorrectly speculated that the moon's closeness to Earth may have affected the giant natural disaster that hit Japan that month.
The phenomenon describes the moment when the New Moon closely matches with perigee.
On February 19, the moon will be 221,734 miles from Earth, as per EarthSky.
Cloud cover should be sparse enough across Illinois, Indiana and Ohio Monday evening and night to allow us to see the supermoon.
The next supermoon viewable from the United Kingdom will take place on the night of Wednesday, February 19.
In general the supermoon will appear 14% larger and 30% brighter than the average moon. January's coincided with a total lunar eclipse-an event where the moon passes directly through Earth's shadow.
