HOW TO ACTUALLY SEE THEM
- Go after midnight; 2–5 AM is the prime window.Louisville turns your side of Earth into the shower's windshield in the small hours.
- Leave the phone in your pocket for 20 minutes.Night vision takes that long to build, and one glance at a screen resets it to zero.
- No equipment. Eyes only: telescopes and binoculars see too little sky. A reclining chair and a blanket beat any optics.
SKY DARKNESS
Bortle 8Bright city sky: expect the Moon, planets, and the brightest stars; faint objects need a trip out of town. Meteors reward darkness more than any other sky sight: a 30–60 minute drive away from the city glow improves the sky by a class or two and multiplies what you'll count.
SAME DAY
The same new Moon, twelve hours earlier
That same afternoon, a partial solar eclipse crosses 16 northern U.S. metros: it misses Louisville, but it's the same new Moon that keeps this night moonless.
Same night, an eclipse in the afternoon →Common questions
When exactly should I watch?
Rates build after midnight and are best between 2 and 5 AM. True darkness in Louisville runs from 10:19 PM to 5:16 AM that night, and the radiant is highest (59°) around 4:59 AM: the last dark hour is the strongest.
Where in the sky should I look?
Nowhere in particular: Perseids streak across the whole sky. Their radiant sits in the northeast in Perseus, 59° up at its best, and meteors look longest about 45° away from it. Lie back and take in as much sky as you can.
Is Louisville dark enough?
Louisville's city-center sky is roughly Bortle 8 (city sky), so expect a fraction of the dark-sky rate downtown. Bright city sky: expect the Moon, planets, and the brightest stars; faint objects need a trip out of town. A 30–60 minute drive away from the city glow improves the sky by a class or two and multiplies the meteors you'll count.
Will clouds block it?
The latest forecast shows 6% cloud cover over Louisville in the core viewing hours. Forecasts firm up as the night approaches; check back the evening before for the final call.
