Observations of a Hybrid Double-Streamer/Pseudostreamer in the Solar Corona View all abstracts by submitter

Laurel Rachmeler   Submitted: 2014-04-04 04:06

We report on the first observation of a single hybrid magnetic structure that contains both a pseudostreamer and a double helmet streamer. This structure was originally observed by the SWAP instrument aboard the PROBA2 satellite between 5 and 10~May~2013. It consists of a pair of filament channels near the south pole of the sun. On the western edge of the structure, the magnetic morphology above the filaments is that of a side-by-side double helmet streamer, with open field between the two channels. On the eastern edge, the magnetic morphology is that of a coronal pseudostreamer without the central open field. We investigated this structure with multiple observations and modelling techniques. We describe the topology and dynamic consequences of such a unified structure.
