The images are either magnetograms taken by the SDO/HMI or EUV observations from SDO or PROBA2. The locations of flares are over-plotted on the images using various routines in SolarSoft, including those developed by the HELIO project; movies are formed by stacking the images together.
 
The centre of the field of view of each image is derived from the location of the active region; this is interpolated from information given in the NOAA/USAF Solar Active Region Summary (included as the noaa_active_region_summary list in the HELIO HEC). The latitude is the average of all values when the region ifs in the list; the longitude is calculated by doing a linear fit to the given longitude (in order to smooth out rounding errors).

 

An image is created every 6 hours using the closest available FITS file to this time that can be found. The time interval coverered by the image is indicated in the bottom left hand corner. Flares for the 48 hours leading up to the time are over-plotted; these are rotated to the time of the FITS image.

 

The locations of the flares over-plotted on the image are derived from the flare catalogue prepared by Lockheed Martin (LMSAL, Palo Alto) and included as the gevloc_sxr_flare list in the HELIO HEC:

 The size of dot indicated the soft X-ray class of the flare – the smallest are C class, medium size are M class and the largest are X class.
 The colour of the dot gives a rough indication of when the flare occurred, with respect to the time in the bottom left of the image. Red dots are up to 12 hours before the time indicated; blue dots are 12-24 hours; turquoise dots are 24-48 hours.
