Surge Prominence in Calcium Light 3rd August

Active region 12121 has been with us now for over 2 weeks, and has been the subject of many images on this website; however yesterday, just as it was sat of the limb of the sun and about to pass out of view from observers on Earth, it put on one final show for us.  Surging jets of plasma were being thrown from this sunspot grouping hurtling out into space.  These are high energy jets and as a result showed up very well in calcium wavelengths in the near ultra violet at 393nm.  Hopefully as the host of active regions that are currently on the face of the sun start to pass over the limb they will also put on a similar spectacle.  Taken with the 40mm scope at 925mm focal length with the DMK31 camera.
