Meteor Showers.....

Recommended Posts

.....tonight at midnight, the Orionids meteor shower.

 

The sky is fairly clear here at the moment........

 

"Though the Orionids are not one of the most spectaculer showers with peak rates around 20 per hour, they are interesting as it is believed that the meteors originate from Comet Halley. It is worth looking out for them for a week around the 21st as the shower is long lived. They will best be seen in the hours before dawn when Orion is high in the southern sky. The star chart shows where they appear to radiate from - called the radiant - at the upper left of Orion, close to the boarder with Gemini. Its best to look almost vertically where the sky is most transparent. Pleasingly, the Moon is not long after new, so its light will not interfere. The Halley meteors are amongst the fastest and enter the upper atmosphere at ~41 km per hour and often leave what are called persistant trains - streaks of ionized gas as the incoming dust particles burn up in the atmosphere. Halley's Comet actually gives us two meteor showers per year as we intersect its orbit twice as the Earth orbits the Sun. The other is in May and the shower is called the Eta Aquarid shower"
