What Kp is needed here?
Orkney Islands sits at a magnetic latitude of approximately 59°N. The Kp index - a global measure of geomagnetic activity on a scale from 0 (quiet) to 9 (extreme storm), updated every 3 hours - needs to reach Kp 3 before the auroral oval expands far enough south to be visible from here.
At Kp 3, visibility is possible from Orkney Islands but skies need to be clear and dark. Cloud cover and light pollution remain the main obstacles even when Kp is high enough.
Best dark sky sites near Orkney Islands
Light pollution is the biggest obstacle after cloud cover. These sites give you the best dark northern horizon within reach.
Hoy island
Orkney's most dramatic island. Very low population, high moorland, and open sea on all sides. A short ferry from Houton gives access to some of the darkest skies in the UK.
Birsay Moor, west mainland
Open peat moorland in the north-west of Orkney mainland. No settlement for miles in the northern direction. The coast at Birsay gives open Atlantic views.
Yesnaby sea stacks, west mainland
Clifftop with dramatic sea views to the north and west. Accessible car park and short walk from the B9056. Very dark after sunset.
Egilsay and outer islands
The smaller outer islands of Orkney are extremely dark. Reachable by ferry from Tingwall. Even Egilsay on the east side faces north over open Orkney Sound.
