My records show I made 281 comet observations of 50 different comets over 72 nights. My worst month was March and the best was August. 72 nights is a lot less than 2017 when I was out on 118 nights.
A clear morning followed by a clear night on the same day counts as one clear night, whereas a clear spell in the evening that spans midnight I count as two clear nights. During last year I changed my observing habit to avoid observing until after midnight because of my neighbours’ nuisance lights that generally go out after they go to bed. This change has probably reduced the number of nights I record as being clear.
I also reported 821 comet astrometric positions to the MPC during 2018.
All the best for 2019
