Here in Essex there were 99 clear dates in 2016. I count clear dates, so a morning and evening observing session on the same day count as 1 clear date, but a nights observing session that spans midnight counts as 2 clear dates. (It would be easier if I used the Julian calendar).
January, February and August tied first with 11 clear dates each, June was the worst with just 2.
I made the largest number of comet observations in November (58) although there were only 9 clear dates, presumably because of the long nights.
I achieved 410 comet observations in total via CCD. Those observations generated about 1200 astrometric measure submissions to the Minor Planets Centre.
