Tonight's full Hunter's Moon won't help people trying to watch
meteors.  More about the Hunter's Moon and a meteor shower -- right
after this.

October 9  The Hunter's Moon and the Giacobinids

Tuesday evening, the full moon rises in the east around sunset.  Since
the Harvest Moon was last month, this full moon bears the name Hunter's
Moon.

The Harvest Moon and the Hunter's Moon both come around the time of the
autumn equinox.  These full moons look entirely or nearly full for
several nights in a row.  Last month, the extra light of the full moon
may have been helpful to some farmers bringing in the harvest.  This
month, the moon is supposed to help hunters.

Well, maybe so.  But the full moon in the sky these few nights won't
help skywatchers trying to glimpse the famous Giacobinid meteor
shower.  These meteors are bits of debris from Comet Giacobini-Zinner
-- the same comet due to be encountered by a NASA spacecraft in
September of next year.  Most meteor showers are named for the
constellation from which they appear to radiate -- and the Giacobinids
are sometimes called the Draconids, since they radiate from the
constellation Draco.  But these particular meteors tend to follow close
behind their comet -- and so they're often called the Giacobinids in
its honor.  During years when the comet is nearby, the Giacobinid
meteor shower can be very spectacular.

Comet Giacobini-Zinner will be in our vicinity next year -- so 1985 may
be a good year for the Giacobinid meteor shower.  That's lucky --
because this year the peak of the shower is Tuesday morning -- and the
full Hunter's Moon will wash out all but the brightest meteors.
