Heaven will be moved this weekend: it's the nights of Leonid Meteor Rain.
Saturday and Sunday, especially at dawn, may be the best times to appreciate them if weather conditions allow it.
It will be a little Luna, so some meteors would go unnoticed, but not all.
And how many will it be? It is not easy to decide. Lejonids sometimes give surprises with major deficiencies, but this time they are expected from 10 to 15 per hour.
Like almost all meteors, it is associated with a comet, Temple-Tuttle.
When the earth crosses one of the pathways of the way in its approach to the sun, the material that is being released is encountered by small grains that cause the characteristic lightning of meteors as they enter the atmosphere and are consumed at high altitudes.
To see them, it's better in a dark place. With the moon's presence you can wait until it's hidden and so the hours before sunrise get the best.
This rain derives its name from the constellation Leo, the lion, as it gives the impression that it came from. However, it is not necessary to know the constellation or just look at it.
It is best to lie down in a comfortable place and have a better view of the whole sky. You can also see some meteors associated with other rains that are less active right now.
The Tempel-Tuttle comet completes a path around the sun every 33 years and releases material every time it enters the inner solar system.
In the 19th century, observers expected a large rain every 33 years. In 1833, say the stories, it was a Leonid superstorm: 100,000 per hour.
Between 1866 and 67 there was another abundant rain, but the same did not happen in 1899.
It was 1966 when another big storm occurred, about 40 to 50 per second, more than 2,400 per hour. A show in 2001 was another good rain, thousands per hour according to observers in North America and Hawaii.
Even though this time is not predicted, one of these characteristics was 10, 15 or more, with a very bright payment night. So go and enjoy.
