Hello,
For me 2016 has been the best year as far as useable nights for observing is concerned since 2007. I work out my observing statistics as a percentage of the number of nights on which I was available to observe, so not on holiday, away from home or whatever. I managed to observe on 121 out of 267 available nights (45.3%). Best months were August and September, both with over 60% while May, October and November were over 50%. January was the worst with only 28%. In total 18950 images were recorded and measured during 609 observing runs, and 2856 spectra recorded during 144 runs.
Clear skies for 2017 – my last night of 2016 is distinctly overcast!
