The year's big meteor shower, the Perseid event, will peak on Saturday night.

In the Bay Area, the event will be best viewed in the hours before midnight Saturday. The waning crescent moon, whose light will be a small interference, will rise at 1 a.m. Sunday.

The following night's display should be good, if not quite as spectacular.

This annual shower is known for its fast and bright meteors, perhaps 50 or more an hour, which should be visible in all parts of the sky.

NASA astronomer Bill Cooke will host a live online chat about the meteors from 8 p.m to midnight Saturday, Pacific time, at www.nasa.gov/connect/chat/perseids_2012.html.
