ИСТИНА

We present a brief list of recently published studies of flares, erupting filaments and prominences where solar optical spectra and filtergrams observed in Ondřejov were used as a source of main or complementary data. The survey contains results obtained with groups of co-authors and encompasses studies of individual solar phenomena, specifications of eruptive filament and plasmoid models, deriving plasma parameters as well as plasma oscillations in prominences. Several possible projects for a near future are also briefly mentioned.
