Today's sun photo shows bands across the surface (See propagation section link - current solar images) . The bands have been there for several days, but I have never seen anything like them in the past. Anyone know if these are really there, or are they some kind of camera/sensor artifact? If real, any ideas what causes them?

Those are 'Heliospheric Anomalous Markings' or 'HAM' bands...
