Derivation of the Magnetic Field in a Coronal Mass Ejection Core via Multi-frequency Radio Imaging
Vourlidas, A.; Tun, Samuel D.
The magnetic field within the core of a coronal mass ejection (CME) on 2010 August 14 is derived from analysis of multi-wavelength radio imaging data. This CME's core was found to be the source of a moving type IV radio burst, whose emission is here determined to arise from the gyrosynchrotron process. The CME core's true trajectory, electron dens…
SWAP Observations of the Long-term, Large-scale Evolution of the Extreme-ultraviolet Solar Corona
Berghmans, David; Nicula, Bogdan; Seaton, Daniel B. +2 more
The Sun Watcher with Active Pixels and Image Processing (SWAP) EUV solar telescope on board the Project for On-Board Autonomy 2 spacecraft has been regularly observing the solar corona in a bandpass near 17.4 nm since 2010 February. With a field of view of 54 × 54 arcmin, SWAP provides the widest-field images of the EUV corona available from the p…
