Use of the source data
- Basis is the corrected real area of a whole sunspot. E.g. this on the 1960-01-01 a value of 350 millionths of the visible Sun's hemisphere.
- The position is also corrected for a better illustration. The displayed 50% latitude is not 45 but 30. The equation is
0.00456273 * (2191.67 - (90 - Abs(lat))^1.7095) * IIf(lat < 0, -1, 1)
- After that the coordinates are rounded to 0.5 units.
- The named unit ppm means the size of millionths of half Sun's hemisphere.
- Areas lower than 2 millionths after the year 1976 are hidden. Because relevant sizes are e. g. 1000 millionths.
- Every year is shown a group of values for each month, that means 12 groups per year. On an Latitude the size of of available spots in a month will be averaged.
