Pivot of the Emerging Bipolar Magnetic Region in the Birth of Sigmoidal Solar Active Regions
Ronald L. Moore, Sanjiv K. Tiwari, V. Aparna +3
We present an augmentation to longstanding evidence from observations and MHD modeling that (1) every solar emerging bipolar magnetic region (BMR) is made by an emerging omega-loop…

Magnetohydrodynamic Simulation of a Coronal Mass Ejection Observed During the Near-radial Alignment of Solar Orbiter and Earth
Talwinder Singh, Dinesha V. Hegde, Tae K. Kim +1
Interplanetary Coronal Mass Ejections (ICMEs) are the primary sources of geomagnetic storms at Earth. Negative out-of-ecliptic component (Bz) of magnetic field in the ICME or its a…
