Using Polarized White Light Triplets Measured by STEREO to Isolate Internal Structure
Abstract
On 2010 April 3, the SECCHI/COR2 coronagraphs on board the twin NASA/STEREO spacecraft observed a coronal mass ejection (CME) in total and polarized brightness white light. It has been suggested that exploiting the full range of white light imagery, including the polarization ratio, may enable reconstruction of CME internal features as well as CME morphology; however, noisy imagery has made this promise difficult to fulfill. Using a recently developed noise-gating process to improve the signal-to-noise ratio in COR2, we demonstrate that we can spatially isolate features within the CME.
