What are the Orionids?
The Orionids are a captivating meteor shower that lights up autumn skies each year. They originate from debris shed by Halley’s Comet as it orbits the Sun, creating bright streaks as tiny particles streak through Earth’s atmosphere.
When to watch
In October, stargazers can catch Orionids from October 2 to November 7. The peak occurs on the night between October 22 and 23, according to the Observatório do Lago Alqueva. This is when the dust trail is densest, offering more meteors per hour.
Peak night details
During the peak, observers can expect more frequent meteors, often 15-20 per hour under dark skies, with a few brighter fireballs. Actual rates vary with moonlight and local weather, but the spectacle remains a highlight of the autumn sky.
Where to watch
To maximize your chances of seeing Orionids, choose a viewing spot far from the glow of cities. Rural fields, hilltops, or designated dark-sky sites provide the best viewing. In Portugal, the Lago Alqueva region is a popular option, but any dark rural area away from streetlights will do.
Viewing tips for families and friends
Plan a relaxed evening: bring blankets, lawn chairs, warm clothing, snacks, and hot drinks. A thermos of something warm helps little ones stay outdoors, comfortable for hours. Allow your eyes to adjust to the darkness for about 15-20 minutes; avoid looking at bright screens, and consider using a small red flashlight to preserve night vision.
Practical tips
Check local weather and moonrise times before heading out. If the Moon is bright, meteor visibility can be reduced, so plan for a little later in the night. No binoculars or telescopes are needed—meteor trails are best enjoyed with the naked eye.
Why this event matters
The Orionids are one of the year’s major astronomical events, offering a reliable annual window to enjoy the night sky with family and friends. Since the dust originates from Halley’s Comet, watching the Orionids connects us with a long cosmic history and the dynamic nature of our solar system.
Plan your October skywatch
Mark your calendar for October 2 to November 7 to catch the Orionids, with the peak on the night of 22-23 October. Gather a group, pick a dark spot, and prepare for a memorable few hours under the stars.
