The Comet C/2025 R3, also known as PanSTARRS, will be visible in the early morning skies over Finland over the coming two weeks, according to the astronomical association Ursa.

In a statement, Ursa explained that the comet is already somewhat visible to the naked eye when the sky is dark, but binoculars or a telescope significantly improve the chances of seeing it.

Usra added that the comet will become about four times brighter by 19 April, with the best observation period expected to be between 10 and 20 April at around 3:30am. The comet will be visible in the morning sky between east and northeast, the association said.

The challenge, however, is that the comet is simultaneously approaching the Sun, and the brightening of the sky makes it more difficult to observe.

The PanSTARRS comet will be closest to the Sun on 19 April, but it's possible that it won't survive the passage intact.

The comet was discovered by the Hawaii-based Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) last September. Its journey towards the Sun has lasted about 170,000 years.
