A recently discovered comet, C/2026 A1 (MAPS), could become visible in UK skies this weekend if it survives a close encounter with the Sun. The sungrazer comet, found in January, will pass extremely close to the Sun's surface on April 4.
If it survives the intense heat, it has the potential to become a 'Great Comet' as bright as Venus. Although its orbit favours the Southern Hemisphere, UK observers may still catch a glimpse under the right conditions.
Before April 4, the comet will be very faint and likely require a telescope or high-end binoculars. After that date, known as 'The Survivor Window', it may reappear in evening skies, but will remain low on the western horizon, requiring a clear view unobstructed by buildings or trees.
The best viewing date is April 5, approximately 30 to 45 minutes after sunset. It will remain visible in the western skies until April 15. While potentially visible to the naked eye, binoculars are recommended due to twilight.
For those who miss MAPS, Comet C/2025 R3 (PanSTARRS) may be visible from April 19 to 26 in the morning sky before sunrise, located in the constellation Pegasus. It is expected to appear as a 'fuzzy star' with a subtle tail.
