Bright night shining clouds - 18.7.2020 at 00.01 - 18.7.2020 at 01.50 Jyväskylä Observation number 92077

Visibility IV / V

Juha Kinnunen, Jyväskylän Sirius

Wider and brighter than the previous bridge: the nights were widely visible on the northern sky before midnight and from there they brightened and strengthened so that they extended from 1-2 east to west at 1-2 o'clock and the upper limit was at its best in zenith.

In the west there was a laundry board, otherwise the shapes were mainly different types of gauze. The movement and shape changes were quite rapid.

It seemed to be as high as 16 degrees and the air was calm.
