2018 was not an unusual year here in Scotland, as astronomical observing and associated note-making are concerned.
Total number of nights where observations were made in 2018: 137
Percentage of nights available for observation in 2018: 37.5 per cent.
2019: I recorded 135 nights of clear or partially clear skies. This represents 36.9 per cent of nights available for observation.
These numbers continue to be in accord with the claims of several British historical observers; T. W. Webb, William F. Denning & Charles Grover.
