Global Transient Coronal Hole Tracking

Advisor: Chris Lowder

Transient coronal holes, or coronal dimmings, are regions that are marked by a drop in intensity as seen in extreme-ultraviolet (EUV) or x-ray wavelength images of the sun. These events can occur in association with coronal mass ejections as a result of magnetic field reconfiguration. Using developed software routines, the student will analyze the evolution of coronal dimming signatures for several associated eruptive events.

Project Goals:
[1] Obtain and process STEREO-A 195A, STEREO-B 195A, and AIA 193A datasets for analysis.
[2] Process datasets through existing code and compile results.
[3] Compare results with global magnetic field extrapolations.
