Quiescent hedgerow prominence
Vacuum Tower Telescope
A quiescent hedgerow prominence located in the northwest solar limb was observed on 2012 September 2 with the slit-jaw camera of the Tenerife Infrared Polarimeter (TIP) installed at the German Vacuum Tower Telescope (Observatorio del Teide, Tenerife, Spain).
The prominence can be identified in the H-alpha slit-jaw images as an extended body with a foot on the right side. The good seeing conditions during the observing time allowed us to distinguish fine-scale structures in the prominence body. They are clearly oriented perpendicularly to the solar limb direction as columns of plasma. We have identified these structures as prominence threads. Below the threads (but above the limb) there is a dark cavity (known as a prominence bubble) where an instability develops, generating an upflow plume.
