Clearly visible night shining clouds - 8.8.2020 at 00.17 - 8.8.2020 at 00.32 Helsinki Observation number 92607

Visibility III / V


A quarter past midnight in the shallow north was a pretty little group, the brightest part of which faded half past one by one. At that point, the Sun was already below -12 degrees. It drops down pretty quickly already, and in a week the observation window will branch out. Timelapse could have recorded the loss of the bright part. In the vivid image situation, the cloud group was no longer visually separated. The observation conditions were quite good. Figures 2 to 5 are from 0:20 to 0:32.

Edit. The situation of the previous night 6 / 7.8.2020 and a few other previous nights was repeated, ie a cloud front rose in the narrow sector of the north visible from the window. It seems to be able to make observations from such an interior: the last picture at 2:49.
