Cycle 24 Equatorial Plage - 17th August

These small bright points are plage, the residual magnetism of cycle 24 on the suns equator.  These will slowly but surely become absent as cycle 24 magnetism is cancelled out and cycle 25 starts to become more prevalent at higher latitudes.  Taken with the 90mm Coronado SolarmaxII telescope double stacked with a Daystar Quark to increase contrast  by reducing continuum leakage.
