Skies should clear enough tonight for a view of the Orionid meteor shower. It returns each autumn as the Earth sweeps through debris left behind by Halley's Comet. The shower peaked this morning but remains at high levels for several days. You could see as many as 23 per hour far from urban lighting. They're fast, often bright, and half of them leave persistent trains. Look east after 10 p.m., but better between midnight and dawn, as the moon sets and the constellation Orion rises high overhead.
