On measurements of the Balmer continuum flux in a solar flare: Analysis of pre-flare and flare pulsations
Original language description
A new ground based device for the measurement of the Balmer continuum flux in solar flares was recently developed and installed at the Ondrejov Observatory. We observed an X1 solar flare on 2014 June 11 during its pre-flare and impulsive phases using a wide band spectrometer with a cadence of 1 s. The Ensemble Empirical Mode Decomposition (EEMD) of the registered signal was performed. We found damped oscillations with a period of 609 s and damping time of 1478 s. Shorter periods of about 30-120 s were found during the pre-flare and impulsive phases, but they might be of non-flare origin.
