Dayside Auroral Activity, Aine Merritt, Gerard J. Fasel
Dayside Auroral Activity, Aine Merritt, Gerard J. Fasel
Seaver College Research And Scholarly Achievement Symposium
The dayside aurora is greatly influenced by the solar wind. Many different types of dayside auroral features have been identified, including poleward-moving auroral forms (PMAFs), throat aurora, shock aurora, and diffuse aurora. This study looks at the dayside auroral activity using the BACC ground-based all-sky-cameras located in both Longyearbyen (Kjell Henriksen Observatory) and Ny-Alesund, Svalbard. There are times when PMAFs peel off the dayside auroral oval in an ordered fashion, elongated east-west arcs moving poleward. At other times, the dayside aurora displays arcs that have extreme brightening moving through the arcs as they exhibit swirls and become a bit chaotic …
Investigating The Correlation Between Inclination Of Coronal Loops And Solar Flare Activity, John-Paul Mann
Investigating The Correlation Between Inclination Of Coronal Loops And Solar Flare Activity, John-Paul Mann
Symposium Of University Research and Creative Expression (SOURCE)
The purpose of this research is to investigate changes in the coronal loop structures during the life cycle of a solar flare. Coronal loops are intricate and complicated magnetic features on the solar surface that are the source of large solar flares. Understanding the dynamics of these coronal loops provides better models for predicting solar flare activity. By obtaining the magnetogram, or magnetic field strength, along with the inclination of these coronal loops, the full structure of the coronal loop can be obtained. Therefore, we studied how the coronal loops inclination angle, as it emerges from the photosphere, changes in …
