On what data is the widget based?

The widget is based on solar-terrestrial data from the National Oceanic and Atmospheric Administration (NOAA). They have a wealth of information available for anyone interested. Among others, they measure solar activity and make it available - as raw text - here: http://www.swpc.noaa.gov/ftpdir/latest/
