Rare Blue Moon may be seen on October 31

The pandemic caused by the new coronavirus has hindered many plans, but it has not prevented us from being able to follow celestial spectacles that continue to take the sky this year. The next event should be the Blue Moon. Famous for being the second full moon in just one month, this phase of Earth’s natural satellite can be seen on October 31st.

The first full moon of the said month should occur on October 1. Although nicknamed blue, it may not really look like this. This is because for such an appearance, the star depends on whether the atmosphere is filled with tobacco powders or particles of a certain size.

But it is worth remembering that, just as there are chances that the Blue Moon will appear to us, there are also chances that this visualization will be impossible. Taking into account that only one full moon should appear per month, after October, this unique feature of the moon can only be seen again in 2039.

Blue Moon

The moon that we will see on October 31 is called the Blue Moon for having developed this aspect on specific occasions: volcanic eruption on Mount Saint Helena, USA, in 1980; at the Mount Krakatona eruption in Indonesia in 1983; and in the eruption of Monte Pinatubo, in the Philippines, in 1991. The events caused the star to present a significant aspect of blue, hence the name’s justification.

But it should be noted that there are actually two types of blue moons. The full moon can be considered blue when the second full moon in just one month. This specific feature makes it called the Monthly Blue Moon, like the one we will have on October 31st. But there is also the Seasonal Blue Moon, when this phenomenon occurs coinciding with the third full moon of four of them in a single season.

Next moons

By the end of the year, the moon should present Earth with other beautiful views. On November 30, there is the Beaver Moon or Moon of the Beaver, characterized by appearing in a period where beavers start building dams to protect themselves. To close the celestial events with a flourish, on December 30 the Cold Moon occurs, which represents the long, cold and dark periods of winter.
