FIREBALLS: The Perseid meteor shower, which peaks this weekend (Aug.
12-13), produces more fireballs than any other known annual meteor
shower. (Fireballs are meteors brighter than Jupiter or Venus.) This
characteristic of the Perseids is important because in 2017 the shower
peaks under the light of a bright gibbous Moon. Perseid fireballs
should be visible in spite of lunar interference, producing a pleasing
display for anyone outdoors before sunrise on Saturday and Sunday.
