Orionids Meteor Shower

Posted October 24, 2009 by User 1

2009 is turning out to be a great year for the Orionids. The Orionids are created by a stream of debris left by Halley's Comet. Normally, this shower is overlooked due to its low peak at just 15 meteors per hour. So far, it's already over a ZHR of 40.

The reason for this wide stream which normally takes Earth 1 day to pass through is believed to be due to a trail laid down by the comet around 1000 BC which has only now reached Earth. We are likely currently passing through the middle of the trail as observations show us at a maximum right now.

Best viewing is had after midnight when the constellation of Orion is well above the horizon. A thin crescent moon should make things easier without the wash of moonlight as had during the Perseids.
