Orionids meteor shower visible overnight in Tennessee Valley
Not busy tonight? How 'bout catching a meteor shower? If you're patient and you don't mind sacrificing a few hours of sleep, you may be treated to some celestial fireworks this week.
Orionid meteors appear every year around this time, when Earth travels through an area of space littered with debris from Halley's Comet. The peak will occur tonight, Wednesday, Oct. 21 into tomorrow morning of Thursday, Oct. 22.
"The Orionids will probably show weaker activity than usual this year," says Bill Cooke of the NASA Meteoroid Environments Office at Marshall Space Flight Center in Huntsville, Ala. "Bits of comet dust hitting the atmosphere will probably give us about a dozen meteors per hour."
The best time to look for Orionid meteors is just before sunrise this Thursday, Oct. 22, when Earth encounters the densest part of Halley's debris stream.
Observing is simple: set the alarm a few hours before dawn, go outside and look up in the direction of the constellation Orion. No telescope is necessary to see Orionids shooting across the sky. While the meteor count may be lower this year, viewing conditions
are favorable, as the gibbous moon will set by 1 a.m. Central time, permitting good viewing just before dawn when rates will be at their highest.
A live stream of the night sky from NASA's Marshall Space Flight Center will be available via Ustream beginning tonight October 21, at 9 p.m. Central. The live feed is an alternative for stargazers experiencing bad weather or light-polluted night skies.
If the weather in Huntsville is clear, Orionids may be seen in the feed as early as 10:30 p.m. Central, though the hours before dawn should show the most Orionid activity.
