About a year ago we had the 1st #covidlockdown in Germany

I'm the stay-home homeschooling dad - my wife is a medical doctor

But I could work @ night which I do often anyway

I did measure the night sky brightness and found it had decreased compared to before lockdown (1/12) so in March 2017 it was less bright than in 2020 (see figure for zenith brightness)

this is surprising because we would expect light emission and #lightpollution to increase like shown in the paper we co-authored with @skyglowberlin and others
