In this paper, we present a multiwavelength analysis to mass draining and oscillations in a large quiescent filament prior to its successful eruption on 2015 April 28. The eruption of a smaller filament that was parallel and in close, ∼350″ proximity was observed to induce longitudinal oscillations and enhance mass draining within the filament of interest. The longitudinal oscillation with an amplitude of ∼25 Mm and ∼23 km s−1 underwent no damping during its observable cycle. Subsequently the… 


Large-Amplitude Oscillation of an Erupting Filament as Seen in EUV, Hα, and Microwave Observations
Abstract We present multiwavelength observations of a large-amplitude oscillation of a polar-crown filament on 15 October 2002, which has been reported by Isobe and Tripathi (Astron. Astrophys.449,
Large amplitude oscillation of a polar crown filament in the pre-eruption phase
Aims. We report observation of a large-amplitude filament oscillation followed by an eruption. This is used to probe the pre-eruption condition and the trigger mechanism of solar eruptions. Methods.
Large-amplitude longitudinal oscillations in a solar filament
In this paper, we report our multiwavelength observations of the large-amplitude longitudinal oscillations of a filament on 2015 May 3. Located next to active region 12335, the sigmoidal filament was
Simultaneous transverse and longitudinal oscillations in a quiescent prominence triggered by a coronal jet
In this paper, we report our multiwavelength observations of the simultaneous transverse and longitudinal oscillations in a quiescent prominence on 2015 June 29. A C2.4 flare took place in active
Large amplitude oscillatory motion along a solar filament
Context. Large amplitude oscillations of solar filaments is a phenomenon that has been known for more than half a century. Recently, a new mode of oscillations, characterized by periodical plasma
Simultaneous longitudinal and transverse oscillations in filament threads after a failed eruption
Context. Longitudinal and transverse oscillations are frequently observed in the solar prominences and/or filaments. These oscillations are excited by a large-scale shock wave, impulsive flares at
Large-Amplitude Longitudinal Oscillations Triggered by the Merging of Two Solar Filaments: Observations and Magnetic Field Analysis
We follow the eruption of two related intermediate filaments observed in H$\alpha$ (from GONG) and in EUV (from SDO/AIA) and the resulting large-amplitude longitudinal oscillations of the plasma in
On a small-scale EUV wave: the driving mechanism and the associated oscillating filament
We present observations of a small-scale Extreme-ultraviolet (EUV) wave that was associated with a mini-filament eruption and a GOES B1.9 micro-fare in the quiet Sun region. The initiation of the
Observations and simulations of longitudinal oscillations of an active region prominence
Context. Filament longitudinal oscillations have been observed on the solar disk in H�. Aims. We intend to find an example of the longitudinal oscillations of a prominence, where the magnetic dip can
Large-amplitude Prominence Oscillations following Impact by a Coronal Jet
Observational evidence shows that coronal jets can hit prominences and set them in motion. The impact leads to large-amplitude oscillations (LAOs) in the prominence. In this paper, we attempt to
