| Evolution of sunspot group NOAA 9830 and positions of flares in it animated by using the data of SOHO/MDI Debrecen Data (SDD) sunspot catalogue (lower panel, middle, ellipses with positions and areas corresponding to the relevant data of spots in SDD and with grey-scale colour coding of the magnetic polarities corresponding to that of the magnetograms), SOHO/MDI continuum images (lower panel, left) and magnetograms (lower panel, right), SOHO/EIT images (upper panel, middle), GOES and RHESSI flare data (red and blue symbols) observed within the interval around the time of SDD data. |
