Perseids
Meteor Shower
Just in case some of you missed Rick Evans’ message
to the planetarium visitors mail list, here it is:
The Sky Is Falling…
The weekend of August 12 and 13 is projected
to host the peak of this years’ Perseids meteor shower. In the past, it
has generally been the biggest meteor shower of the year. So the anticipation
of this year’s meteor shower is growing. You don’t need a telescope,
or even binoculars to view this spectacular celestial event. On those nights
go out to a dark location, away from the city, and you’re likely to see
many, many more meteors than usual. The thin crescent Moon sets early on
the evening of August 12th, leaving the sky fully dark for this year’s
Perseid meteor shower. You'll see dozens of fast, bright shooting stars
that appear to come from the northeast.
Meteors are commonly referred to as "shooting
stars" or “falling stars” because they quickly cross our skies. Appearing
as streaks of light. In reality, these streaks are caused by space
rocks, usually no bigger than a grain of sand. They're tiny bits of dust
and rock that collide with Earth. They are moving so fast -- many thousands
of miles per hour -- that they usually burn up in Earth’s atmosphere. When
they burn up they make a brief, bright streak in the sky, which scientists
call a "meteor."
Every once in a while the Earth moves through
a part of its orbit where there is lots of dust and bits of rock, and when
that happens we get a lot more meteors. We call that a "meteor shower"
and the Perseids meteor shower, which occurs in the middle of August every
year, is one of the best.
Most of the meteors show up between midnight
and sunrise. That’s when the radiant (the part of the sky between
the constellations Perseus and Cassiopeia from which the Perseids appear
to come) is highest in midnorthern latitudes. In fact, it could be as often
as every minute that you might a tiny fire burning through the sky. Skywatchers
can expect to see 60 or more Perseids per hour, provided the sky is very
clear and dark. If you miss the Perseids that weekend, don’t give up. The
shower lasts for two weeks or so, with excellent rates in the predawn hours
of August 10th through August 15th.

Hoping to see everyone at the meeting,

P.S. It looks like EarthLink is not going
to budge on their Procrustean policy of reduced server space allocations.
My only communication from them has been via automated and form-reply e-mail
non sequiturs.
Thanks to those who offered their server space,
but I’m afraid that would be a logistical nightmare for me. So until
I can make some other arrangements, some of the current AAS Web pages will
have to come down. I’ll return to posting the archived Astrofiles
as soon as I get back under the new 10MB limit.
