Via vedur.is, Iceland: Aurora Forecast tips, Jóhanna M. Thorlacius - The Aurora Borealis requires dark & clear skies. IMO provides combined info on Aurora activity, cloud cover, sunlight & moonlight, in order to provide forecasts - the scale changes in accordance with the date selected under the cloud cover map. Even grade 2 can be beautiful & grade 3 dazzling. The image was shot by Þórður Arason at the island Flatey, Breiðafjörður Bay, W Iceland 092313 22:39.  [ posted by Mr. TRONA ]
