Origin of extreme solar eruptive activity from the active region NOAA 12673 and the largest flare of solar cycle 24
Bhuwan Joshi, Prabir K. Mitra
During 2017, when the Sun was moving toward the minimum phase of solar cycle 24, an exceptionally eruptive active region (AR) NOAA 12673 emerged on the Sun during August 28-Septemb…
Pre-flare coronal jet and evolutionary phases of a solar eruptive prominence associated with M1.8 flare: SDO and RHESSI observations
Bhuwan Joshi, Upendra Kushwaha, Astrid Veronig +1
We investigate triggering, activation, and ejection of a solar eruptive prominence that occurred in a multi-polar flux system of active region NOAA 11548 on 2012 August 18 by analy…
Onset and evolution of solar flares: Application of 2D and 3D models of magnetic reconnection
Bhuwan Joshi, Prabir K. Mitra, Astrid M. Veronig +1
The contemporary multi-wavelength observations have revealed various important features during solar flares which, on one hand, support the two-dimensional (2D) "standard flare mod…
Source Region and Launch Characteristics of Magnetic-arch-blowout Solar Coronal Mass Ejections Driven by Homologous Compact-flare Blowout Jets
Binal D. Patel, Bhuwan Joshi, Alphonse C. Sterling +1
We study the formation of four coronal mass ejections (CMEs) originating from homologous blowout jets. All of the blowout jets originated from NOAA active region (AR) 11515 on 2012…
Comparison of the Hall Magnetohydrodynamics and Magnetohydrodynamics evolution of a flaring solar active region
Kamlesh Bora, Ramit Bhattacharyya, Avijeet Prasad +2
This work analyzes the Hall magnetohydrodynamics (HMHD) and magnetohydrodynamics (MHD) numerical simulations of a flaring solar active region as a testbed while idealizing the coro…
North-South Distribution of Solar Flares during Cycle 23
Bhuwan Joshi, P. Pant, P. K. Manoharan
In this paper, we investigate the spatial distribution of solar flares in the northern and southern hemisphere of the Sun that occurred during the period 1996 to 2003. This period…
