Letterkenny mountaineer John Coyle was joined by his own shadow during a snowy hike up Errigal last week.
A Brocken spectre is a rare light phenomenon that occurs on mountains when a person’s shadow is cast in front of them onto clouds or mist.
The strange and sometimes spooky figure is usually surrounded by a circular halo.
John was lucky to get the chance to see the image for long enough to capture it on camera. Watch here:
The Brocken Spectre light event was named after the Brocken mountain in Germany, where the weather effect was first recorded.
A very specific combination of conditions is needed for the figure to appear.
John said: “I have seen the Brocken spectre on many occasions down through the years but generally the effect lasts for a few seconds only.
Conditions last Saturday were good for the hike with a little snow high up on Errigal and just a light dusting on Muckish.”
