Leonids Meteor Shower

November 17, 2021 all-day America/Chicago Timezone

Unfortunately the nearly full moon will dominate the sky this year, blocking all but the brightest meteors. Best viewing will be from a dark location after midnight.

The Leonids is an average shower, producing up to 15 meteors per hour at its peak. This shower is unique in that it has a cyclonic peak about every 33 years where hundreds of meteors per hour can be seen. That last of these occurred in 2001. (So I guess start making plans for November 2033?)

The Leonids is produced by dust grains left behind by comet Tempel-Tuttle, which was discovered in 1865. The shower runs annually from November 6-30. It peaks this year on the night of the 17th and morning of the 18th. Meteors will radiate from the constellation Leo, but can appear anywhere in the sky.
