Cycle Variation in the Occurrence of Great Soft X-ray Solar Flares
V. N. Obridko, M. M. Katsova, D. D. Sokoloff
Powerful nonstationary processes such as flares and coronal mass ejections are detected mainly near the solar cycle maxima. However, the analysis of the great flares since 1975, wh…
Do Planets Affect the Behavior of the Long-term Solar Activity?
M. M. Katsova, V. N. Obridko, D. D. Sokoloff +1
Solar activity is a process driven by many independent but interconnected phenomena. Although the 11-year cycle is the result of operation of the dynamo mechanism, the cause of lon…
Resonances and Stellar Cycles: Observations and Modelling
M. M. Katsova, F. A. Azizov, V. N. Obridko +2
In the paper we discuss the possibility of the influence of parametric excitation, in particular, planetary gravitational interaction, on the behavior of stellar magnetic activity…
North-South Asymmetry of the Solar Activity at Different Spatial Scales
V. N. Obridko, A. S. Shibalova, D. D. Sokoloff +1
Solar activity seems quite understandable when considered on the scales comparable with a solar cycle, i.e. about 11 years, and on a short time scale of about a year. A solar cycle…
Some comments on the matching of photometric and magnetic properties of structures at the solar surface
V. N. Obridko, D. D. Sokoloff, M. M. Katsova
We investigate sharply outlined features recorded in solar magnetic field tracers. It is shown that the magnetic boundaries of a sunspot do not coincide with the photometric ones.…
