Where they come from: Comet Tuttle (8P/Tuttle)

Dust from Comet Tuttle, which comes round every 13.6 years. A quiet shower most years, around the winter solstice, with now and then a burst of much higher rates.

The estimate is how many you might really see from a dark spot here, allowing for how high the shower climbs and for moonlight. "Under a perfect sky" is the best case. The bar also counts the forecast cloud at the best time, so a clouded-out night sits at the bottom, as does rain on the radar now.

From most of the Northern Hemisphere it never sets, so you can watch it all night.
