The Solar and Geomagnetic Storms in May 2024: A Flash Data Report
Hisashi Hayakawa, Yusuke Ebihara, Alexander Mishev +16
In May 2024, the scientific community observed intense solar eruptions that resulted in a great geomagnetic storm and auroral extension, highlighting the need to document and quant…
The Effects of Oscillations & Collisions of Emerging Bipolar Regions on the Triggering of Solar Flares
Callum Boocock, Kanya Kusano, David Tsiklauri
The ability to predict the occurrence of solar flares in advance is important to humankind due to the potential damage they can cause to Earth's environment and infrastructure. It…
Improvement of solar cycle prediction: Plateau of solar axial dipole moment
H. Iijima, H. Hotta, S. Imada +2
Aims. We report the small temporal variation of the axial dipole moment near the solar minimum and its application to the solar cycle prediction by the surface flux transport (SFT)…
A Plasma β Transition Within a Propagating Flux Rope
Neel P. Savani, A. Vourlidas, D. Shiota +4
We present a 2.5D MHD simulation of a magnetic flux rope (FR) propagating in the heliosphere and investigate the cause of the observed sharp plasma beta transition. Specifically, w…
Nonlinear Force-Free Extrapolation of the Coronal Magnetic Field Based on the MHD Relaxation Method
S. Inoue, T. Magara, V. S. Pandey +4
We develop a nonlinear force-free field (NLFFF) extrapolation code based on the magnetohydrodynamic (MHD) relaxation method. We extend the classical MHD relaxation method in two im…
A study of the Heliocentric dependence of Shock Standoff Distance and Geometry using 2.5D MHD Simulations of CME-driven shocks
Neel P. Savani, Daikou Shiota, Kanya Kusano +2
We perform four numerical magnetohydrodynamic simulations in 2.5 dimensions (2.5D) of fast Coronal Mass Ejections (CMEs) and their associated shock fronts between 10Rs and 300Rs. W…
Decorrelation Times of Photospheric Fields and Flows
Brian T. Welsch, Kanya Kusano, Tetsuya T. Yamamoto +1
We use autocorrelation to investigate evolution in flow fields inferred by applying Fourier Local Correlation Tracking (FLCT) to a sequence of high-resolution (0.3 \arcsec), high-c…
