The 2D H-alpha spectral data of the spray-like eruptive prominence (EP) of March 5, 1991 are obtained and analyzed quantitatively by means of the 'multi-cloud model' (MCM) method. Four physical quantities (i.e. the column number density of hydrogen a

In the present work, the north-south asymmetry of solar activity was examined by analyzing statistically the hemispheric distribution of annual numbers of sunspot groups, using the Royal Greenwich Observatory data set from the year 1874 through 2000.

In the present study we have produced a diagram of the latitude distribution of sunspot groups from the year 1874 through 1999 and examined statistical characteristics of the mean latitude of sunspot groups. The reliability of the observed data set p

We have collected a set of predicted values of maximum sunspot numbers of solar cycles 22 and 23 published in the literature and examined the characteristics of predictions made by various methods. The precursor methods are found to be always superio

A solar Stokes spectrum telescope has been built and is routinely used to measure full Stokes spectra of solar surface features. Its optical and electronic systems are outlined while the polarization analyzer is described in detail. The observations

The D3 emission lines observed on a prominence over the solar east limb on 1984 May 5, which were found to consist of two components, i.e. the main and the broadened components, have been successfully calculated using the two-cloud model method with

The problem of line formation in stellar atmospheres is studied in terms of contribution functions. The correlation between the contribution from atmospheric layers to an emergent quantity and the line formation process is explored in the case of abs

Characteristics of latitude migration of sunspot groups in the northern and southern hemispheres are investigated by using the Royal Greenwich Observatory data set from the years 1874 through 1999. Latitude migration of sunspot groups is found to be
