Sunspot areas and tilt angles
Listed in IVOA Registry (Virtual Observatory)
Extending the knowledge about the properties of solar cycles into the past is essential for understanding the solar dynamo.
Description
This paper aims to estimate areas of sunspots observed by Schwabe in 1825-1867 and to calculate the tilt angles of sunspot groups. The sunspot sizes in Schwabe's drawings are not to scale and need to be converted into physical sunspot areas.
We employed a statistical approach assuming that the area distribution of sunspots was the same in the 19th century as it was in the 20th century.
