Evolutionary aspects and north-south asymmetry of soft X-ray flare index during solar cycles 21, 22, and 23
Bhuwan Joshi, R. Bhattacharyya, K. K. Pandey +2
Aims. In this paper, we investigate the temporal evolution and north-south (N-S) asymmetry in the occurrence of solar flares during cycle 21, 22, and 23, and compare the results wi…
Formation and eruption of a flux rope from the sigmoid active region NOAA 11719 and associated M6.5 flare: A multi-wavelength study
Bhuwan Joshi, Upendra Kushwaha, Astrid M. Veronig +3
We investigate the formation, activation and eruption of a flux rope from the sigmoid active region NOAA 11719 by analyzing E(UV), X-ray and radio measurements. During the pre-erup…
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…
Large-scale contraction and subsequent disruption of coronal loops during various phases of the M6.2 flare associated with the confined flux rope eruption
Upendra Kushwaha, Bhuwan Joshi, Astrid M. Veronig +1
We present a detailed multi-wavelength study of the M6.2 flare which was associated with a confined eruption of a prominence using TRACE, RHESSI, and NoRH observations. The pre-fla…
Impulsive energy release and non-thermal emission in a confined M4.0 flare triggered by rapidly evolving magnetic structures
Upendra Kushwaha, Bhuwan Joshi, Kyung-Suk Cho +3
We present observations of a confined M4.0 flare from NOAA 11302 on 2011 September 26. Observations at high temporal, spatial, and spectral resolution from Solar Dynamics Observato…
RHESSI and TRACE observations of multiple flare activity in AR 10656 and associated filament eruption
Bhuwan Joshi, Upendra Kushwaha, K. -S. Cho +1
We present RHESSI and TRACE observations of multiple flare activity that occurred in the active region NOAA 10656 over the period of two hours on 2004 August 18. Out of four succes…
