An updated review on theoretical research on the role of magnetic fields in prominences is presented. It is concluded that the theory of the Hanle effect has...

We analyzed multiline observations of a quiescent prominence from the slit spectrograph located at the Ondřejov Observatory. Dopplergrams and integrated...

Observational evidence shows that coronal jets can hit prominences and set them in motion. The impact leads to large-amplitude oscillations (LAOs) in the...

Techniques involved in measurements of solar magnetic field are based on the observation and interpretation of the polarization signal in suitable Fraunhofer...

Both linear and nonlinear analysis are used to gain a better understanding of the effects of multi-dimensional transfer of energy by radiation in spatially...

On 20 August 2010 an energetic disturbance triggered damped large-amplitude longitudinal (LAL) oscillations in almost an entire filament. In the present work we...

A photometric study of umbral bright features (umbral dots, clusters of umbral dots, bright grains of light bridges) in sunspots is presented. It is based on...

The width distribution of the penumbral filaments is estimated using white light photographs obtained with a vacuum, Newtonian type telescope. Observations were...

This book includes four chapters devoted to techniques and interpretation of solar observations. The chapter on high spatial resolution techniques considers...
