This huge prominence placed a beautiful show on the Solar's limb. Please not that at the left side of the main prominence there is another prominence with a helix shape, resembling a tornado.
Regarding solar activities, it can not be assured if prominence will actually detach causing a big mass ejection or if it will return to the solar chromosphere.
