Unipolarity of the solar magnetic field in equatorial coronal holes
Khagendra Katuwal, R. T. James McAteer
A study of the unbalanced magnetic polarity distribution of 70 coronal holes was performed. Data from the Helioseismic and Magnetic Imager (HMI) were used to examine the photospher…
Spatial and temporal analysis of 3-minute oscillations in the chromosphere associated with the X2.2 Solar Flare on 2011 February 15
Laurel Farris, R. T. James McAteer
3-minute oscillations in the chromosphere are attributed to both slow magnetoacoustic waves propagating from the photosphere, and to oscillations generated within the chromosphere…
The Slowly Varying Corona. II. The Components of F and Their Use in EUV Proxies
S. J. Schonfeld, S. M. White, C. J. Henney +2
Using four years of full-disk-integrated coronal differential emission measures calculated in Schonfeld et al. (2017), we investigate the relative contribution of bremsstrahlung an…
Segmentation of Coronal Holes Using Active Contours Without Edges
L. E. Boucheron, M. Valluri, R. T. J. McAteer
An application of active contours without edges is presented as an efficient and effective means of extracting and characterizing coronal holes. Coronal holes are regions of low-de…
A Comparison of Flare Forecasting Methods, I: Results from the "All-Clear" Workshop
G. Barnes, K. D. Leka, C. J. Schrijver +15
Solar flares produce radiation which can have an almost immediate effect on the near-Earth environment, making it crucial to forecast flares in order to mitigate their negative eff…
Evolution of a Current Sheet in a Solar Flare
Chunming Zhu, Rui Liu, David Alexander +1
We report multi-wavelength and multi-viewpoint observations of a solar eruptive event which involves loop-loop interactions. During a C2.0 flare, motions associated with inflowing…
