Last night, the SQM meter could record during a short clearing in the clouds a value of SQM 21. It seems too good to be thru! If the data is correct, it’s probably not spectacular, but symbolically a milestone in our fight around local light pollution. Major sources of pollution, like the Hoegaarden InBev brewery and the Tienen sugar refinery have reduced their output significantly over the years. In addition the local town has switched off public lighting after midnight during the week. Now also the public lighting is modernized towards LED, with fixtures that have a much better light distribution. Also unnecessary light points were removed.
Update 29/10: again the SQM meter went over SQM 21 last night. So now it starts to be a little suspicious! SQM 21,19 seems to high a value. Will check!!
