The Decay of Two Adjacent Sunspots Associated with Moving Magnetic Features
Yang Peng, Zhike Xue, Zhongquan Qu +4
The relationship between the decay of sunspots and moving magnetic features (MMFs) plays an important role in understanding the evolution of active regions. We present observations…
Eruptions of Two Coupled Filaments Observed by SDO, GONG and STEREO
Z. K. Xue, X. L. Yan, Z. Q. Qu +2
On 2012 July 11, two solar filaments were observed in the northeast of the solar disk and their eruptions due to the interaction between them are studied by using the data from the…
Kink instability evidenced by analyzing the leg rotation of a filament
X. L. Yan, Z. K. Xue, J. H. Liu +4
Kink instability is a possible mechanism for solar filament eruption. However, the twist of a solar filament is very difficult to directly measure from observation. In this paper,…
Sunspot rotation, filament, and flare: The event on 2000 February 10
X. L. Yan, Z. Q. Qu, D. F. Kong +1
We find that a sunspot with positive polarity had an obvious counter-clockwise rotation and resulted in the formation and eruption of an inverse S-shaped filament in NOAA active re…
Relationship between eruptions of active-region filaments and associated flares and CMEs
X. L. Yan, Z. Q. Qu, D. F. Kong
To better understand the dynamical process of active-region filament eruptions and associated flares and CMEs, we carried out a statistical study of 120 events observed by BBSO, TR…
The phase relation between sunspot numbers and soft X-ray flares
X. L. Yan, L. H. Deng, Z. Q. Qu +1
To better understand long-term flare activity, we present a statistical study on soft X-ray flares from May 1976 to May 2008. It is found that the smoothed monthly peak fluxes of C…
