Weather: Super Blue Moon, astronomy show continues! All information
But what is one Blue supermoon? We tell you right away, don’t expect to see a blue moon as in the picture above, only in your children’s drawing papers you can see it, if they want, in this shade.
So why is it called a blue supermoon?
First of all, have one Supermoon When our satellite is in the full moon phase (full moonAt the same time (or a few hours apart) at the closest point to Earth (rock bottom). On these occasions, we will notice that the moon will be slightly larger than normal (7-10% more) and therefore its brightness will be greater (10-13% more).
But why blue? (excellent)blue moon It actually only comes from its supposed rarity, especially from the English expression “Once in a blue moon” (once every blue moon), which is intended to refer to something that does not occur commonly (although the phenomenon actually occurs every 3-5 years).
Over the years, two definitions of a (super) blue moon have spread: the origin is the one that is attributed to it The third full moon in a season contains four. However, later on, the same definition also spread for The second full moon in one monthsuch as the one we will admire on the last day of August (the first happened on August 1).
This second definition is, in fact, the result of an error: the confusion was first made by the amateur astronomer. James Hugh Bruett (1886-1955), who misunderstood the basis for calculating the “true” blue moon, writing that it was the second full moon in a single month in a magazine article Sky and telescope in 1946. This misidentification has spread ever since, especially after it was mentioned on the famous radio program called star history, in 1980 and then appeared as an answer in the 1986 version of the board game Petty pursuit.
Today, however, it is now considered one Second definition Instead of error.
Weather information and forecast – in 3.35 on 31 August The supermoon has reached its maximum phase, but it can also be seen in the evening.
The weather is generally improving, which is why most Italians will be able to easily observe it.
