Perseids 2028
The Perseids peak on 12 August 2028, 14:30 UT, with up to about 110 meteors an hour under a perfect dark sky, coming from Cassiopeia. The Moon is about 59 percent lit and waning at the hour we state it for (12 August 2028, 14:00 UT).
Sets the map's clock to 12 August 2028, 14:00 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, 110 for the Perseids) 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 14:00 UT on 12 August 2028 the Moon is 59 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.

- Computed here, not yet the IMO's: the maximum is when the Sun reaches the solar longitude the IMO Meteor Shower Calendar 2027 gives (140.0°, J2000); the 2028 calendar was not out on 2026-11-08, read 8 November 2026
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.
