Three-minute Sunspot Oscillations Driven by Magnetic Reconnection in a Light Bridge
Donguk Song, Jongchul Chae, Hannah Kwak +5
We report a different type of three-minute chromospheric oscillations above a sunspot in association with a small-scale impulsive event in a light bridge. During our observations,…
Observation of a Large-scale Quasi-circular Secondary Ribbon associated with Successive Flares and a Halo CME
Eun-Kyung Lim, Vasyl Yurchyshyn, Pankaj Kumar +7
Solar flare ribbons provide an important clue to the magnetic reconnection process and associated magnetic field topology in the solar corona. We detected a large-scale secondary f…
Solar Multiple Eruptions From a Confined Magnetic Structure
Jeongwoo Lee, Chang Liu, Ju Jing +1
How eruption can recur from a confined magnetic structure is discussed based on the {\it Solar Dynamics Observatory} (SDO) observations of the NOAA active region 11444, which produ…
Solar Eruption and Local Magnetic Parameters
Jeongwoo Lee, Chang Liu, Ju Jing +1
It is now a common practice to use local magnetic parameters such as magnetic decay index for explaining solar eruptions from active regions, but there can be an alternative view t…
Chromospheric Plasma Ejections in a Light Bridge of a Sunspot
Donguk Song, Jongchul Chae, Vasyl Yurchyshyn +5
It is well-known that light bridges inside a sunspot produce small-scale plasma ejections and transient brightenings in the chromosphere, but the nature and origin of such phenomen…
