In a rare celestial event set to unfold tonight, sky-gazers are in for a treat as they witness a stunning display of meteors, comets, and the Northern Lights all painting the sky in a mesmerising dance. With the Orionid meteor shower at its peak and Comet Lemmon (C/2025 A6) and Comet C/2025 R2 SWAN making their closest approach to Earth, the night promises to be a spectacle beyond imagination. Add to that mix the possibility of faint glows of Aurora Borealis, and you have a cosmic show that holds something for everyone, whether an experienced stargazer or a curious onlooker.

The Orionid meteor shower, a result of debris from Halley’s Comet, will streak across the heavens, lighting up the night sky with its dazzling display of light. Comet Lemmon will add its own green glow to the west-northwest sky after sunset, while Comet SWAN will also make an appearance further east. As conditions align perfectly for this cosmic convergence, there’s a chance that the Northern Lights might make an appearance, painting the high-latitude skies with hues of green and pink.
Aurora enthusiasts and sky-watchers alike have reason to be excited, as the Northern Lights are expected to be visible across parts of Canada and the northern United States. Increased geomagnetic activity, propelled by two coronal mass ejections from the Sun, has upped the chances of witnessing this natural light show. The best viewing window is set to begin after sunset and extend deep into the night, offering ample opportunity to catch a glimpse of the elusive Aurora Borealis.
Having two visible comets in the night sky is indeed a rare treat for astronomers and space enthusiasts. Comet Lemmon will make its appearance low in the west-northwest horizon, accompanied by Comet SWAN slightly higher and towards the northeast. Both comets are set to be visible shortly after sunset, providing a unique opportunity to witness these cosmic wanderers as they grace the night sky with their presence.
For those eager to witness the Orionid meteor shower, the peak viewing window spans from midnight to just before dawn overnight, offering the chance to see around 10 to 20 meteors per hour under dark skies. While the shower can be seen worldwide, the best views are anticipated from areas with minimal light pollution. Looking towards the east to northeast, where the Orion constellation rises, promises the optimal chance to catch a glimpse of shooting stars lighting up the night.
As the stage is set for this celestial extravaganza, the advice for eager sky-watchers is simple yet crucial – find a dark open area to allow your eyes to adjust, have patience, and keep an eye out for updates on the Kp index for real-time information on the potential stretch of the Northern Lights. Whether capturing the event through a camera lens or savouring the moment with the naked eye, tonight’s sky promises to be a canvas of natural wonders that will leave observers spellbound by the beauty and grandeur of the universe.
