|Leonid Meteor Shower 2002 - Your Planning Guide
The Leonids are the main meteor event of the year. The Leonids (LEO) are
debris from Comet Tempel-Tuttle. The Leonid Meteor Shower occurs every year when
the earth passes through this old comet debris. The earth intersects the path of
this debris from November 14th until the 21st, with a special concentration of
debris hitting the earth's upper atmosphere around November 18th and 19th.
The Leonids are an incredible meteor shower - take a look at some of the best
images from last year's display over Japan and you will see what we mean. The
photos are by Shigemi Numazawa are magnificent: http://www1.nisiq.net/~numazawa/nippou/leo01e.html
Much has been written about this year’s event in the current issues of the
astronomy magazines in North America, and there are many good articles and
online links. The November 2002 Leonids are very special, as they may well be
the last chance to see a real meteor 'storm' in our lifetime! Mark November 18th
and 19th on your calendars now!
So, what makes this year special? In 2002, the rates are predicted to be much
higher than normal. In fact, they are predicted to hit 'storm' level, of at
least several thousand meteors per hour, for several short durations of time!
This activity is in addition to the much lower general Leonid meteor rates over
the period November 14th to 21st.
The radiant of the Leonids meteor shower, i.e., the area in the sky where the
meteors will seem to come from, is at 153 degrees, ie. RA 10h 12m, Dec +22,
which is up in the 'sickle' of the constellation of Leo. That is why they are
Leonid meteors are extremely fast, with a velocity of about 71 km per second.
You can see a map of the radiant on the website of the International Meteor
Organization (IMO) at http://www.imo.net/calendar/cal02.html#Leonids
as well as a link to the IMO's special 2002 Leonids page: http://www.imo.net/leo02
A very interesting graphical representation of predicted rates by the main
research teams can be found on the website of Hiroshi Ogawa, of the University
of Tsukuba, Japan. He plots meteor rates on world maps, using colored grid lines
for easy reference. A definite site to check out! http://homepage2.nifty.com/~baron/leo02forcast.htm
Perhaps the best single website for the 2002 Leonids is that of Dr. Peter
Jenniskens and the Leonid MAC team at http://leonid.arc.nasa.gov.
The site provides a wealth of information on the Leonid meteor shower, its
parent comet, and the researchers and experiments flying on the NASA airborne
So what do you really need to know about the predicted Leonid meteor storm in
November? Let us fill you in!
How many meteors will we really see, and when?
Where do we have to go to see the Leonids?
What equipment do we need for observing?
For recording meteors, what should we record?
Where can we get more specialized information?
