Today was mostly cloudy, but there were sufficient clearings between clouds to permit a solar imaging session. Today’s H-alpha image shows prominence activity along the SE, NW, and SW solar limbs. The activity along the SW limb consists of spicules – hairlike structures of sun stuff exploding above the chromosphere.
Prior images have shown these delicate spicule structures, but I have not pointed then by name before.
The sunspot image shows no new active regions. This sunspot cycle is quieting down.
Today’s prominence cameos appear in the gallery below. Note the spicules in the third panel.
