Dim night shining clouds - 23.5.2020 at 00.10 - 23.5.2020 at 01.15 Helsinki Observation number 90765

Visibility II / V


Noise, a promising-looking group in the north at about 10 degrees.

Edit. There were features of the miniature show at the first observation of the season. It lasted over an hour and was extensive. The stars stood out in the pictures, but I couldn’t begin to measure the exact coordinates. In the last picture, there is probably the same group that rose quite high 1:15 above the roofs of the 3-storey house. There is a suspicious redness in the lower belts, though.

Hienoa, yöpilvimies on herännyt talviunestaan :)

Juu, mutta eihän tässä ole ollut moneen kuukauteen oikein mitään havaittavaa.
