Overview
- The maximum is expected overnight on November 17–18 as Earth passes through debris from comet 55P/Tempel-Tuttle.
- Forecasters call for a steady display of roughly 10–15, up to about 20, meteors per hour rather than a storm.
- Viewing is best from midnight to dawn when the radiant in the constellation Leo rises higher in the sky.
- Leonid meteors are among the fastest at about 70 km per second and can leave vivid, green-tinged trails.
- The shower remains active through late November, with the clearest views from dark sites after 15–20 minutes of eye adjustment.
