Orionid meteor shower to peak in UK skies this week

The Orionid meteor shower, known for producing bright fireballs, will peak in the UK skies this week. This celestial event has been active throughout October, with the best viewing expected on October 22. Under clear skies, skywatchers could witness between 10 and 20 meteors per hour. However, even in less favorable weather conditions, the shower will remain visible until November 7.

The Orionids are an annual meteor shower caused by debris from Halley's comet, which Earth passes through each year. As the debris burns up upon entering our atmosphere at speeds of around 41 miles per second, it creates bright streaks of light and long glowing trails. To observe the Orionids, find a dark location away from city light pollution, let your eyes adjust to the night sky for 20 minutes, and look for meteors radiating from the constellation Orion near the star Betelgeuse.

Despite the Moon being in the waxing gibbous phase on October 21, improving conditions after it sets around 03:00 BST on Thursday morning should provide better viewing opportunities. However, this week is expected to be the wettest and windiest so far in autumn, with low pressure systems bringing rain and clouds across the UK. While Wednesday may remain wet and windy for many parts of the UK, some clear spells might appear in England, Wales, and Northern Ireland during the second half of the night into Thursday morning.

Western Scotland may also offer a chance for clear skies. Eastern Scotland and the far south coast of England are expected to remain cloudy and wet. For the best chance of seeing the Orionids, check the latest weather forecast or consult the BBC Weather app.
