Is there a connection between plages and sunspots?
A) No. Sunspots are a photospheric phenomenon, while plages occur in the chromosphere.
B) Yes. The magnetic fields that result in sunspots in the photosphere continue on up through the chromosphere where they produce plages.
C) Yes. The magnetic fields that result in sunspots in the photosphere compress the gases above the photosphere, and this pressure creates plages in the chromosphere.
D) Yes. The 5- minute oscillations of the photosphere push the sunspots up into the chromosphere every 5 minutes and thus results in plages.
