Orionids 2027
The Orionids peak on 22 October 2027, 00:40 UT, with up to about 20 meteors an hour under a perfect dark sky, coming from Orion. The Moon is about 58 percent lit and waning at the hour we state it for (22 October 2027, 00:00 UT).
Sets the map's clock to 22 October 2027, 00:00 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, 20 for the Orionids) 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 00:00 UT on 22 October 2027 the Moon is 58 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.
