The Blue Supermoon will be the biggest and brightest full moon of the year. This unique event in the lunar cycle is extremely rare. It means that the silver globe will be very close to the Earth, but it also ignores the rules of the calendar.
Supermoon
A supermoon is a full moon when the silver globe is exceptionally close to the Earth, and we already had such a phenomenon in the first days of August. However, he is preparing an even better replay for us when he is even closer.

The position of the moon relative to our planet can vary by more than 40,000 km. While circling the Earth, it can go as far as 405,500 km at apogee, while its approach to perigee means a distance of 363,400 km.
A silver globe “becomes” a supermoon if it approaches us at 90% of its capacity. We then perceive its disk as larger (the diameter is up to 8% longer than usual) and especially bright.
Blue Supermoon 2023
We will be able to see this phenomenon again in a few days. On the night of August 30/31, the Moon will be full and will be at a distance of 363,603 km from Earth. Seeing it as a supermoon, however, will require some sacrifices. The silver globe will appear fully at 2:35 our time, and the moon is predicted to set at 4:06.
Those who value a night’s rest, however, will not lose much if the weather is good the next evening. On August 31, the Moon will move away from the Earth, but by less than 1,000 km. We can expect its sunrise at 20:00 and that’s when the best moments will come supermoon sightings.
It will be low over the horizon, and moving between buildings and trees, it will create an optical illusion for us. His shield will seem especially huge. Towering will occur 36 minutes after midnight and set at 5:43 am on September 1. It would be hard to expect a nicer end to the holiday.
Blue Moon (Blue Moon)
As if that wasn’t enough, the Moon in the last days of August will contradict the rules of the calendar we use. It will be full for the second time this month and will become the so-called Blue Moon. It means “extra” or “off-season” full moon.
This is no anomaly. The lunar cycle lasts 29 and a half days, which does not correspond to our monthly measure of time. So there is Black February, when the Moon never appears to us at full, and every 2-3 years we have a month when we see it like this twice.
Such extra full moons occur 44 times in 100 years and we can expect repetitions of August 2023 from the Moon in almost 2 years, in May 2026. However, we can hear about the Blue Moon much earlier.
By another definition Blue Moon it is the third full moon of four that occur at the same time of year. According to this recipe for the Blue Moon, we will see it in the summer of 2024. The silver globe will be full then 4 times: June 21, July 21, August 19 and September 18. Since August’s full moon is the third full moon of the summer series, it can also be called a blue moon.
However, don’t expect the face of the moon to be blue or blue. The name Blue Moon is just a common one and probably comes from the Old English word belewe (belewe). It means the moon is trying to deceive people. It indicates to us that a new month has started, when it is not.
