A comparative analysis of sunspot sizes in sunspot groups was performed. For this analysis, we used the database of characteristics of individual sunspots and pores according to observations at the Kislovodsk Mountain Astronomical Station (KMAS) and

The properties of solar bipoles based on data from magnetic field observations at Mount Wilson Observatory during the period of 1917–2016 are considered. Special attention is given to variations in the size of the bipole magnetic axis during the so

The results of the digitalization of the centennial series of solar activity are considered. The data contain information on sunspots since 1918, sunspot umbra since 1917, plages since 1907, and spectral corona since 1939. In particular the digitaliz

Digitization of the daily prominence sketches based on data from the global observational network of visual solar spectroscopes was performed for 1922–1934. More than 55000 prominences were distinguished. The results of analysis of distributions by

The preliminary results of solar filaments distinguished in daily H-alpha observations at Kodaikanal (1912–2002) are presented. To mark the boundaries of solar filaments, methods based on automated procedures of marking low-contrast objects on the

Long-term measurements of sunspot magnetic fields have been analyzed with the use of the Mount Wilson Observatory (MWO) data based on the digitization of the magnetic field strength (B) and umbra and pore areas from 1918 to 2014. Time variations in t

We use recently digitized sunspot drawings from Mount Wilson Observatory to investigate the latitudinal dependence of tilt angles of active regions and its change with solar cycle. The drawings cover the period from 1917 to present and contain inform
