The Orionid meteor shower peaks tonight. The meteors are rocks and sand left behind by Halley’s comet. It has been going on for a week now, but tonight is the peak in terms of frequency of meteors.
This is best viewed after the moon sets and before dawn, so your best bet in the U.S. in the wee hours just before sunrise. Around midnight (when I go to bed) the moon will be high in the sky, masking all but the brightest meteors. I’ll go out and look, though, if the sky is clear.
