The rain of stars of the Orion arrives with the full moon

The observation of meteor rain - popularly known as rain of stars - of the Orion is complicated this October for its coincidence with the full moon.

The Oriones will have their peak maximum the nights of October 20 and 22, as Detailed Bill Cooke, head of the NASA Meteoroid Environment Office.

Specifically he has pointed out "around 20-25 meteors per hour when the rain reaches his maximum point during the early morning of October 21".

However, clarity in the heavens caused by the plenilunium will make their observation more complicated.

The fireballs of the Orion leaves incandescent debris currents that last several minutes. Such filaments of "meteorum smoke", twisted by the winds in the upper atmosphere, adopt twisted forms that may even be more cute than meteor themselves.

The Oriones have their origin in the famous Halley Comet. The Earth passes through a current of dusty debris that come from the Kite Halley and the sky, before dawn, can be illuminated with a beautiful display of shooting stars.

Cooke points out that it is "one of the most beautiful rains of the year" because they come out of the Orion constellation. The cause is its surroundings: the rain is surrounded by the brightest stars of the sky. Constellations like Taurus, Gemini and Orion bring a brilliant backdrop for the show.

This autumn can be enjoyed two other meteor rains. As Rafael Bachiller, director of the National Astronomical Observatory, LEÓNIDAS and GERMINES, will take place in very unfavorable conditions for his observation as the moon will significantly illuminate the sky background attenuating the glitter of the meteors.

LEÓNIDAS will reach its maximum activity around November 17, only two days before the full moon, while the twinings will have its maximum on December 13, that is, with the moon already very grown that will reach the plenilunium the day 19.
