If skies are clear between midnight and the first glimmer of dawn this weekend, you may get to see up to 20 celestial fireworks per hour from the Orionid meteor shower. While far from the richest of the annual shooting star displays, the Orionids are particularly swift and have their genesis in particles strewn along the orbit of Comet Halley.
The highlight of October for meteor observers is the Orionid meteor shower, which occurs when the Earth encounters the debris stream of Halley’s Comet. With a broad maximum 21-23 October, peak rates are typically about a quarter of those seen for the Perseids of August. A good percentage of Orionids are bright and leave persistent trains.
