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.

When you want to zoom in on one of the images, simply
