A Few Shooting Stars in November

During the last few years we were all anxiously awaiting
November because of the continued potential for some residual
leftovers from the Leonid meteor storm that reached its peak in
2001. Unfortunately we'll have to wait until 2031 to 2033 for the
next major storm. Presently we'll have to be content with somewhere
between 15 to 20 meteors per hour. With a rate that low, you better
observe this shower with a friend or you'll soon fall fast asleep.
Yes, we got spoiled with the high meteor activity we experienced
for a couple of years, but the above listed rates are normal for
the Leonids between storm level periods. Before I highlight the
specifics of this now mediocre meteor shower, lets see what other
astronomical events can be seen during November.
First up is the Taurid meteor shower. This shower, comprising
both a northern and a southern component, spans several weeks.
However it is most active from the 3rd to the 12th. Early in this
time frame the Moon will be at last quarter, then shrinking to New
on the 12th. Moonlight will therefore only slightly interfere with
observing this minor meteor shower.
Though the Taurids are slow meteors, entering our atmosphere at
only 17-miles per second, these shooting stars are also bright.
More often than not they are yellow in color. Fairly frequently
they become fireballs that fragment into multiple meteors. This
characteristic alone makes them worth watching. Expect five to ten
Taurids per hour.
At mid-month, on the night of November 16-17, the peak of the
Leonid meteor shower occurs. I wish I could say that astronomers
have found another new and previously unknown dense stream of
particles getting ready to pulverize our atmosphere, but research
has not revealed such a scenario.
Even though the crescent Moon will set early on the 16th, the
best time to view the Leonids are after midnight. With no Moon to
spoil the view, you should have no difficulty in seeing 10 to 15
Leonids per hour from a dark location.
Leonid meteors blaze across the sky at an amazing speed of 44
miles per second. No Leonid has been known to reach the ground as
a meteorite because they are completely annihilated upon entry into
our protective atmosphere. Leonids are greenish and bluish meteors,
usually bright, with half of them leaving trains of dust which
persist for minutes. Like the Taurids earlier in the month, Leonids
often produce fireballs as well.
Remember, Seagrave Observatory is open free of charge to the
public every clear Saturday night. I'd advise you to visit soon
before winter settles in. First, The Old Farmer's Almanac has
predicted a bad winter for us, and secondly the National Weather
Service has recently done likewise. With the early and bountiful
snow last year, then the brutal cold during February, and then
there was the rainy late March which left our parking lot a small
pond, we didn't reopen Seagrave Observatory until the second week
in April!!! So come out for a visit before Mother Nature causes us
to hibernate once again! Check our web site -

keep your eyes to the skies.
