Activity is already picking up; last night NASA's network of all-sky meteor cameras recorded 16 Perseid fireballs over the USA. A fireball is a very bright meteor, at least as bright as the planets Jupiter or Venus.

No other comet produces fireballs like 109P/Swift-Tuttle--probably a result of its oversized nucleus. The comet's core is 26 km in diameter, and naturally crumbles into fireball-sized chunks. Since 2008, NASA has counted more fireballs from the Perseids than any other shower:

I thought this interactive visualization of Swift-Tuttle was fun to adjust and play with.
You can put in a date of 8/1/2125 and see the comet pass close to Earth.
