Coming up
- Perseids meteor shower12 August · in 7 daysPeak night. The summer favourite — up to ~100/hour, warm nights.
- Total solar eclipse12 August · in 7 daysOnly visible along a narrow track on Earth — check whether it passes near you (never look at the Sun unprotected).
- Partial lunar eclipse28 AugustA shadow crosses part of the Moon — visible wherever the Moon is up at the time.

- Leonids meteor shower17 NovemberPeak night. Fast and bright, ~15/hour.
Meteor showers are best on a moonless night away from town lights — use the moon panel above to judge. Eclipse and shower dates are worldwide; whether it’s above your horizon depends on your location and time.
Every time is shown in Kos’s own local clock, with daylight saving applied for the date. “—” means the event doesn’t occur (for example, some nights the moon doesn’t rise); “stays light” means the sky never reaches that stage (northern summer). ISS pass times use live orbital data and show only passes visible to the naked eye (bright enough, in a dark-enough sky). Planet visibility is judged during the genuinely-dark window, not by a daytime high point — so a planet only appears here when you could actually see it.
