Clearly visible night shining clouds - 22.7.2011 at 03.30 Turku Observation number 862

Visibility III / V

Joni Tahkoniemi, Ursa (Länsi-Suomi)

An early awakening to work and I happened to visit from the balcony looking at the sky and after all there were a few isolated belts NNW. Then know what would have been to the north when I couldn’t see it from the balcony.

03:30: NNW, 20-40, IIb 3
