|Meteor Counting for Dummies|
Astronomers have made a prediction: On Tuesday morning, Nov. 19th, sky watchers in Europe and North America will see hundreds or thousands of meteors streak across the sky during the annual Leonid meteor shower. A dazzling show!
But which is it? Hundreds of meteors? ... or thousands?
You be the judge!
If you can count, you can help NASA decide whose predictions are correct.
Before you rush outside to start counting,
however, there are a few procedures we need review to ensure
that the counts are scientifically meaningful. The number of
meteors you see depends on the light pollution in your area,
the altitude of the shower's radiant, whether or not the moon
is up, etc. All these need to be recorded so we can make sense
of the observations and compare results from different observers.
The full moon will be out on Nov. 19th.
Try not to stare at it--it will ruin your night vision. Instead,
look away from the moon toward a darker patch of sky.
