Clearly visible night shining clouds - 27.6.2022 at 00.40 - 27.6.2022 at 02.15 Helsinki Observation number 107388

Visibility III / V

In the beginning, the area covered by the night clouds was indeed small, but it expanded and then moved all the time, still remaining strictly to the north. Figure 1 was taken at 1:20 a.m. when the area was at its widest. Figure 2 is a timelapse of approximately 90 frames over the entire observation period.

Edit: corrected observation time (00.40 instead of 00.14)
