Actually, Kat, the Leonid is very much like the Leonid! LOL!

I meant to say the Perseid meteor shower usually lasts for 4 or 5 days, so I'd expect the Leonid to, also.

The Perseid and Leonid meteor SHOWERS occur every year (at least within our lifetimes), but some years are more spectacular than others. This year's Perseids were exceptional, as were both last year's and this year's Leonids.

It is a particular meteor STORM that happened this morning, when the earth passed through the tail of some comet during the normal Leonid time. That's what is not expected again for a century.

PS. even though the rain is stopping in Portland, the skies are expected to be at least partly cloudy all week, so even if the showere continues, we won't see much this year.
