Object of the Month: Orionid Meteor Shower
In the hours after midnight on both October 20 & 21 before dawn the Orionid Meteors will be present. Originating near the bright star Betelgeuse in Orion, an observer under dark skies can expect 10 to 20 meteors per hour. This year the last quarter moon will be present whose light shouldn’t pose too much of a problem with seeing the Orionids as they enter the Earth’s atmosphere.
The Orionids are fast moving meteors which often provide a train lingering behind as the fall. This shower is also known for producing some bright fireballs.
The best time to watch the shower is around 2 a.m. This is when the radiant of the shower will be highest in the sky. …see the chart below.
