This is generally one of the mellow meteor showers, typically producing around 35 meteors an hour at its peak. But it has been known to surprise astronomers with more-intense meteor storms in 1933 and 1946.
There also is much more to the shower than meets the eye. The shower, from Comet 21P/Giacobini-Zinner, on a 6.6-year orbital swing around the sun, only yielded about 35 meteors an hour visually. But radar picked up a peak encounter rate of about 150 meteors an hour – a substantial number of no-seeums, objects too small to generate much heat and light as it encounters Earth's atmosphere.
