REPORT OF THE 
Values 1, 2, and 3 are assigned according as they are “visible/’ 
“clear,” or “very clear.” Absence in July leaves a blank for 
that month. For the first time they were seen in December. 
The year was unusually clear, April and May remarkably so. 
March was much below the average. 
Auroras were notably frequent in the Spring, but less 
conspicuous in the Autumn, when the number of sunspots 
unexpectedly began to fall off. Eighteen were recorded in all, 
or the same number as last year. The dates were, January 2nd, 
24th, 30th, February 13th, 20th, March 28th, April 25th, 30th, 
May 1st, 25th, August 12th and 24th, September 21st, 28th, 
October 13th, 17th, 18th, December 11th, 16th. That of April 
25th was very fine ; so also were those of January 2nd and 
August 12th, as seen in Yorkshire. Mock Suns were noted on 
March 6th, April 1st, 4th, 30th, and December 7th. The 
much rarer Mock Moon was seen on May 1st. 
We are again indebted to Henry Richardson, Esq., for 
additional tables of Rainfall, and to Richard Thompson, Esq., 
for additional tables of Bright Sunshine. Although the total 
for the latter at Oswaldkirk was nearly fifty hours less, the 
per-centage was greater. This was because of the usual winter 
excess, 58 hours having been recorded in December, or 29 
per cent.
