The Open Flux Problem
Jon A. Linker,Ronald M. Caplan,Cooper Downs,Pete Riley,Zoran Mikic,Roberto Lionello,Carl J. Henney,Charles N. Arge,Y. Liu,Marc L. DeRosa,Anthony R. Yeates,Mathew J. Owens +11 more
TL;DR: In this article, the authors estimate the open magnetic flux entirely from solar observations by combining automatically detected coronal holes for Carrington rotation 2098 with observatory synoptic magnetic maps.
Numerical investigation of a coronal mass ejection from an anemone active region: reconnection and deflection of the 2005 august 22 eruption
Noé Lugaz,Noé Lugaz,Cooper Downs,Kazunari Shibata,Ilia I. Roussev,Ayumi Asai,Tamas I. Gombosi +6 more
TL;DR: In this article, the authors present a numerical investigation of the coronal evolution of a coronal mass ejection (CME) on 2005 August 22 using a three-dimensional thermodynamic magnetohydrodynamic model, the space weather modeling framework.
Numerical Investigation of a Coronal Mass Ejection from an Anemone Active Region: Reconnection and Deflection of the 2005 August 22 Eruption
Noé Lugaz,Noé Lugaz,Cooper Downs,Kazunari Shibata,Ilia I. Roussev,Ayumi Asai,Tamas I. Gombosi +6 more
TL;DR: In this article, a 3D thermodynamics magnetohydrodynamic model, the SWMF, was used to model the coronal evolution of a coronal mass ejection (CME) on 2005 August 22.

Sun-to-Earth MHD Simulation of the 14 July 2000 "Bastille Day" Eruption
Tibor Torok,Cooper Downs,Jon A. Linker,Roberto Lionello,Viacheslav S. Titov,Zoran Mikic,Pete Riley,Ron Caplan,Janvier Wijaya +8 more
TL;DR: In this paper, a magnetohydrodynamic (MHD) simulation of the 14 July 2000 Bastille Day eruption was presented, which produced a very strong geomagnetic storm.
Synchronic coronal hole mapping using multi-instrument EUV images: Data preparation and detection method
TL;DR: In this paper, a method for the automatic mapping of coronal holes (CH) using simultaneous multi-instrument EUV imaging data is described, including PSF deconvolution and the application of data-derived intensity corrections that account for center-to-limb variations (limb brightening) and interinstrument intensity normalization.
