Simultaneous Observations of Solar Prominence Oscillations Using Two Remote Telescopes

Popis výsledku v původním jazyce

We present the first results of the joint Polish-Czech observational campaign devoted to simultaneous observations of prominence oscillations. As was shown earlier by other authors, not all of the observed periodicities in the Doppler signal come from solar sources (seeing and slight changes in the position of the spectrograph slit may have a significant influence). To exclude false signals, we performed simultaneous observations of the same object on the Sun using two independent telescopes. On 23 September 2010, a quiescent prominence on the north-eastern part of the solar limb was observed with two distant solar telescopes: the Large Coronagraph installed at the Biakw Observatory, Poland, and the Horizontal Telescope at the OndA (TM) ejov Observatory, Czech Republic. Of the many detected periods, the periods of 26, 31, and 55 min unquestionably originate in the prominence, but other periodicities are spurious. Proper detection of periodicities in prominences is crucial for modelling wave propagation and movements in the solar plasma, as well as for seismologically inverting prominence structures and physical parameters.
