Looking Up

From Wiki:

The famous Perseid meteor shower has been observed for about 2000 years, with the first known information on these meteors coming from the Far East. In early Europe, the Perseids came to be known as the "tears of St. Lawrence."

The shower is visible from mid-July each year, with the greatest activity between August 8 and 14, peaking about August 12. During the peak, the rate of meteors reaches 60 or more per hour. They can be seen all across the sky, but because of the path of Swift-Tuttle's orbit, Perseids are mostly visible in the northern hemisphere.

To experience the shower in its full, one should observe in the dark of a clear moonless night, from a point far outside any large cities, where stars are not dimmed by light pollution. The Perseids have a broad peak, so the shower is visible for several nights. On any given night, activity starts slowly in the evening but picks up by 11 p.m., when the radiant gets reasonably high in the sky. The meteor rate increases steadily through the night as the radiant rises higher, peaking just before the sky starts to get light, roughly 1½ to 2 hours before sunrise.

Charles,

What a great post!

BTY Moulton is just such a place as you describe where light pollution from the west and east doesn't cause interference with star gazing too much.

p.s. I keep thinking I'll look up someday and see a coke advert as big as the moon, but it hasn't happened yet.

Aren't they fabulous? We watched them from the Giant's Steps on the Maine coast one August.

Alas... all we're getting this year is rain in Vermont. We probably won't get to see them.
