✦ Synopsis

Heliographic coordinates of several small but stable sunspots, which were determined at five different observatories in 1979, are compared. Some systematic differences within these results are found, which suggest a more detailed analysis of the data accumulation procedures and the physical interpretation. The same holds for the rotation velocities derived from the position data. * Mitteilungen aus dem Kiepenheuer-Institut Nr. 230.

The question is studied whether the one-year solar oscillation found by V. F. Chistyakov for the years 1965-1973 can be traced in the observations of sunspots of 1874-1971 published by Greenwich Observatory. The result is negative. But the study leads to the following two conclusions: (1) The averag

Using two original copies of Hevelius' 'Selenographia' and reducing spot positions with two different methods, we found that the solar angular rotation velocity at the beginning of the Maunder minimum was about the same as today. The gradient of the differential rotation was slightly steeper than gi
