The Old Farmer's Almanac notes that the Wishram people of the Pacific Northwest referred to the Snow Moon as "Shoulder to Shoulder Around the Fire Moon", and that the Cherokee people of the Southeast referred to it as the "Bone Moon". It is the closest, biggest and brightest moon of the year. In a given year, between two and four full moons can be classified as "supermoons".
The Super Snow Moon will peak on 19 February 2019 at 21:23 pm.
While there will be another supermoon in March, this week's will technically be the closest and therefore the biggest of the year. "You can maybe tell the difference from a normal full moon if you make a practice of looking at a lot of them" - something Hartigan said is true for him.
February 19's full moon is the second lunar spectacle in a supermoon trilogy.
At its farthest point, at apogee, the Moon sits roughly 252,088 miles (405,696km) from Earth.
Unfortunately it won't be quite as colourful as last month's super wolf moon - but it's promised to still be quite the natural display, nonetheless.
The first supermoon was the "Blood Wolf Super Moon" on January 21 and the third will take place on March 21.
Fox News reported that the moon will rise at 5:46 p.m.
The moon won't be completely full until 10:53 a.m. EST Tuesday.
Although closer to the Earth, the February 19 supermoon will not be as colorful as last month's 'super blood Moon" eclipse that saw the Earth "s natural satellite turn a stunning shade of red.
Although the super snow moon will be at its fullest on Tuesday morning, it'll still be visible from Sunday night through to Tuesday evening, appearing around 14% largest and 30% brighter than usual.
