On a Flat-shape Emission in the Solar Flare on 7th June 2012

Popis výsledku v původním jazyce

We present results of the study of the C1.5 solar flare(SOL2012-06-07T05:56) which occurred on June 7, 2012. This weak flare showed an extraordinary long flat emission in the X-ray flux curve in the 3-12 keV energy band. Duration of this flat period wasabout 10 minutes while the duration of the flare was almost 20 minutes. As this particular shape was observed both by RHESSI and FERMI, it could not be caused by an instrumental effect. We analyzed the optical spectra and slit-jaw images from the solar spectrograph in Ondřejov and in the hard X-ray by RHESSI as well as EUV data obtained by SDO and all available microwave data. We found that the "flat emission" period was also observed in microwaves (5-17 GHz). During this period the motion of the flaresource from the spot to south direction was revealed.
