Today’s H-alpha image shows the greatest amount of prominence activity along the sun’s SW and W limbs. The dramatic prominence activity that has dominated the ENE limbs the past five days has subsided.
Today’s sunspot image shows a new active region, AR4254, near the sun’s eastern limb. AR4251 is not visible in either my image or NASA’s image, but I have placed a label where we could expect to find it, if it were.
The most remarkable of today’s prominences are showcased in the gallery below. The first frame shows small arches of sun stuff along the ENE limbs. The second shows a tall jet of sun stuff reaching into the corona high above the chromosphere. The last frame shows arcades of sun stuff along the sun’s western limb.
