Search for Possible Connections of Sunspot Features and Torsional Waves
J. Muraközy, A. Ludmány
The torsional oscillation is a well established observational fact and there are theoretical attempts for its description but no final solution has yet been accepted. One of the po…
Development and morphology of leading-following parts of sunspot groups
J. Muraközy, T. Baranyi, A. Ludmány
The detailed sunspot catalogues, the DPD and SDD allow to study the leading and following parts of sunspot groups separately. We examine the equilibrium distance of the two parts,…
Temporal Variations of Coriolis-turns in the Photosphere
J. Muraközy, A. Ludmány
Correlations have been studied between longitudinal and latitudinal shifts of sunspot groups in the period 1986-1998. This study is based on the Debrecen Photoheliographic Data (DP…
Considerations on the Spörer-diagram - torsional wave relationship
J. Muraközy, A. Ludmány
Studies on the earlier reported spatial correlations between magnetic field distributions and the torsional wave have been substantially extended to the period 1975-2009. The inves…
North-south differences of solar cycles
J. Muraközy, A. Ludmány
A long-term variation is detected in the north-south differences of the solar activity, the phase difference of hemispheric cycles alternates by four Schwabe cycles. This variabili…
Variations of Solar Non-axisymmetric Activity
N. Gyenge, T. Baranyi, A. Ludmány
The temporal behaviour of solar active longitudes has been examined by using two sunspot catalogues, the Greenwich Photoheliographic Results (GPR) and the Debrecen Photoheliographi…
