Formation and Eruption of Filament Channel in Solar Active Region 12975: Insights from Observations and Simulations of Magnetic Field Evolution
Dinesh Mishra, P. Vemareddy, Brajesh Kumar
We studied the magnetic field evolution of active region (AR) 12975 using a time-dependent magnetofrictional (TMF) model. This AR produced two consecutive CMEs associated with M-cl…
Understanding the formation and eruption of sigmoidal structure through data-driven modeling of magnetic evolution in solar active region 13500
P. Vemareddy, S. Nair, S. Gosain
We investigate the magnetic origin of the coronal mass ejection (CME) that occurred on November 28, 2023, at 19:50UT from active region (AR) 13500 located near the solar disk-cente…
An intense geomagnetic storm originated from stealth Coronal Mass Ejection: remote and observations by near radially aligned spacecraft
P. Vemareddy, K. Selva Bharathi
We investigate the solar origin and heliospheric evolution of an intense geomagnetic storm that occurred on March 23-24, 2023. Despite multiple candidate CMEs observed between Marc…
Visible Emission Line Coronagraph (VELC) onboard ADITYA-L1
Jagdev Singh, R. Ramesh, B. Raghavendra Prasad +21
Aditya-L1, India's first dedicated mission to study the Sun and its atmosphere from the Sun-Earth Lagrangian L1 location was successfully launched on 2023 September 2. It carries s…
