    We present spectra and slit-jaw images of limb and on-disk eruptive events observed with a high temporal resolution by the OndA (TM) ejov Observatory optical spectrograph. Analysis of the time series of full width at half-maximum (FWHM) in H alpha, H beta, and radio and soft X-ray (SXR) fluxes indicates two phenomenologically distinct types of observations which differ significantly in the timing of FWHM and SXR/radio fluxes. We investigated one such unusual case of a limb eruptive event in more detail. Synthesis of all observed data supports the interpretation of the H alpha broadening in the sense of regular macroscopic plasma motions, contrary to the traditional view (emission from warm dense plasma).
