Visibility V / V

Jorma Koski, Ursa (Helsinki)

The bright night cloud play was about to begin. At 11:41 p.m., the latitude was 120 degrees and the height from the horizon was 20 degrees northwest and northeast. 8/1/2011 at 12:50 it was already so bright that the shutter speeds had to be shortened so that the images would not burn out when the surrounding sky is already quite dark.
