Meteor Shower to Grace California’s November Skies
The Leonid meteor shower will be
making its annual appearance in the California skies in mid-November.
Astronomers expect the shower to begin around 11:15 p.m. on November 16 and to
peak a few hours later, about 1:00 a.m. on November 17.
The shower should
begin and peak again the following night at about the same times.
expect the Leonids to put on a good show.
“If the predictions hold true, you should be able to see several dozen
meteors per hour around midnight on November 17 and November 18,” says
Robert Naeye, editor of “Mercury” magazine, which is published in
San Francisco by the Astronomical Society of the Pacific (ASP).
meteors are particularly beautiful because they can leave long glowing trails
that can persist for several minutes.
These trails look great in binoculars.”

Dr. James White, the executive director of the ASP.

The key, says White, is to pick the direction that provides the darkest
and least obstructed view of the sky and stick with it.
“People miss many
meteors during a shower by trying to watch the entire sky.
Just sit, relax,
and enjoy the show.”

This year’s Leonid meteor shower is really two showers in one, says
astronomer Dr. Peter Jenniskens of NASA’s Ames Research Center in
Moffett Field, California.
The Leonid meteors come from debris left behind by

shower occurs when Earth goes through one of these trails.
According to Jenniskens, the shower on November 16 – 17 will be from
Comet Tempel-Tuttle’s 1932 passage through the inner Solar System.
November 17 – 18 shower will be from the comet’s 1866 passage.

clear, it will be a really nice event for people to go out and see,” says
“It will be interesting to see which of the two nights is

Its membership is spread over all 50 states and
70 countries and includes professional and amateur astronomers, science
educators, and the general public.
The ASP publishes “Mercury,” a teachers’
newsletter called “Universe in a Classroom,” and a technical journal.
