A quick capture during a clear mid summer night. An “advantage” of the light polution here: even so astronomical twilight isn’t reached, the sky brightness is for approx. 3 hours in the range of SQM 19.5 to 19.9. SQM 20.0 is the maximum I measured in my backyard in spring 2020 with the excellent “lock-down” skies.
Hopefully a break in the currently cloudy and rainy weather for some additional O3 und S2 data during the next days before the moon returns.

Has been down before, of course, in 2019. ;-)
