[cayugabirds-l] 2021 Perseid Meteor Shower Info.

[Peter Saracino]

This meteor shower will probably produce the greatest number of meteors on
the mornings of August 11, 12 and 13. On the peak mornings in 2021 – in the
early morning hours, when the most meteors will be flying – there’ll be no
moon to ruin on the show.
Clear skies!
