Leonids 2027
The Leonids peak on 18 November 2027, 06:02 UT, with up to about 15 meteors an hour under a perfect dark sky, coming from Leo. The Moon is about 80 percent lit and waning at the hour we state it for (18 November 2027, 06:00 UT).
Sets the map's clock to 18 November 2027, 06:00 UT and flies to the Moon.

Where to look from your place
Choose a city to see what this looks like from there. With scripts off, the map's Tonight view works out the same for the place you set in it.
What to expect
The rate quoted for a shower (its ZHR, 15 for the Leonids) is what one observer would count in an hour under a perfect dark sky with the radiant overhead: from a town, or with the radiant low, it is a fraction. Lie back, look at a wide patch of sky away from lights, give your eyes twenty minutes, and expect meteors from any part of the sky, all tracing back to the radiant.
What the Moon will do
At 06:00 UT on 18 November 2027 the Moon is 80 percent lit and waning. That is for anywhere on Earth; whether it is up from your place, and how high, is in the box above.

Measured or computed? Dates of the showers and of the eclipses are computed with Astronomy Engine, the same library the map uses, and were read by a person on 9 October 2026. The Moon's percentage is computed. Rates are the IMO's and are not predictions of what you will count.
