The on Friday, called ‘Blue Moon’, is a full moon as any. The plug ‘blue’ is only used to refer to that in the same month will be two full moons, so this star will be as usual, in gray, white or silver.
The phenomenon is explained by the fact that each lunar cycle lasts 28 days, so if Moon a month earlier, is probably a second at the end.
According to NASA, the last time there was a ‘Blue Moon’ was the August 31, 2012 and, after today, a similar astronomical event will be repeated 31 January 2018.
Although the term ‘blue’ finally speaks no color change in how we see this star, if there phenomena in which the Moon itself has seen that color, mainly after volcanic eruptions, such as occurred in 1883 after an earthquake Krakatoa volcano in Indonesia, whose ashes made the moon look like this.
Also, similar phenomena occurred in 1983 after the eruption of the El Chichon volcano in Mexico and in 1980 after the eruption of Mount St. Helens.
Similar phenomena have also been seen in areas devastated by forest fires, which causes changes in the tone of the reflection of the moon.
However, it is not the case of the phenomenon of Friday. The so-called ‘Blue Moon’ will, if weather conditions permit, as is usual and not as portrayed.
