Presented at the 85th
AAVSO Annual Meeting, November 2, 1996
The AAVSO sunspot number
has served as a measure of solar activity on a time scale of decades.
Nevertheless, this paper presents four ways in which the current AAVSO handling
of sunspot data could be improved: (1) publishing error bars; (2) requiring new
sunspot observers to use small apertures and high magnification; (3) using a
logarithmic, rather than linear, average of the scaled sunspot counts; and (4)
publishing all raw data and all procedures.
