Aims. We search for extreme-ultraviolet (EUV) brightenings in TRACE 171 A images and hard X-ray (HXR) bursts observed during failed eruptions. We expect that if an eruption is confined by interaction with overlaying magnetic structures, we should observe effects caused by reconnection between magnetic structures and acceleration of particles. Methods. We used TRACE observations of three well-observed failed eruptions. A semi-automated method was used to search for abrupt brightness changes in… 
Multi-Wavelength Observations of a Failed Filament Eruption and Associated Hovered Coronal Mass Ejection
Failed filament eruption remains mysterious on its initiation, magnetic environment, and erupting and failing mechanisms. We present multi-wavelength observations of a failed filament eruption and
Magnetic structure of solar flare regions producing hard X-ray pulsations
Abstract We present analysis of the magnetic field in seven solar flare regions accompanied by the pulsations of hard X-ray (HXR) emission. These flares were studied by Kuznetsov et al. (2016) (Paper
Large-scale contraction and subsequent disruption of coronal loops during various phases of the M6.2 flare associated with the confined flux rope eruption
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-flare phase of this
Searching for failed eruptions interacting with overlying magnetic field
Abstract It is well known that not all solar flares are connected with eruptions followed by coronal mass ejection (CME). Even strongest X-class flares may not be accompanied by eruptions or are
Confined Flares in Solar Active Region 12192 from 2014 October 18 to 29
Using the observations from the Atmospheric Imaging Assembly (AIA) and Helioseismic and Magnetic Imager (HMI) aboard the Solar Dynamics Observatory (SDO), we investigate six X-class and twenty-nine
Multiwavelength Observation of a Failed Eruption from a Helical Kink-unstable Prominence
Multi-wavelength observations of prominence eruptions provide an opportunity to uncover the physical mechanism of the triggering and the evolution process of the eruption. In this paper, we


Solar impulsive EUV and UV brightenings in flare footpoints and their connection with X-ray emission
Context. The thick-target model of the impulsive phase of solar flares describes the propagation of non-thermal electron beams into the chromosphere. The stopping depth of the electron is related to
Solar impulsive soft X–ray brightenings and their connection with footpoint hard X–ray emission sources
We have investigated 46 solar flares showing impulsive soft X–ray brightenings in footpoints. To obtain their main observational characteristics we used the Yohkoh /SXT images. The results are
We present an observational study on the impact of the dynamic evolution of kinking filaments on the production of hard X-ray (HXR) emission. The investigation of two kinking-filament events in this
A Quadruple Magnetic Source Model for Arcade Flares and X-Ray Arcade Formations outside Active Regions I. Dark Filament Suspension and the Magnetic Structure in the Pre-Event Regions
The high-sensitivity, wide dynamic-range observations by the Soft X-ray Telescope (SXT) aboard Yohkoh has enabled us to look into the faint pre-event structures of arcade flares, and of even fainter
Evidence of Magnetic Reconnection in Solar Flares and a Unified Model of Flares
The solar X-ray observing satellite Yohkoh has discovered various new dynamic features in solar flares and corona, e.g., cusp-shaped flare loops, above-the-loop-top hard X-ray sources, X-ray plasmoid
The Hard X-ray Telescope (HXT) for the SOLAR-A mission
The Hard X-ray Telescope (HXT) is a Fourier-synthesis imager; a set of spatially-modulated photon count data are taken from 64 independent subcollimators and are Fourier-transformed into an image by
A time series of filament eruptions observed by three eyes from space: from failed to successful eruptions
We present stereoscopic observations of six sequential eruptions of a filament in the active region NOAA 11045 on 2010 Feb 8, with the advantage of the STEREO twin viewpoints in combination with
Failed Eruption of a Filament as a Driver for Vertical Oscillations of Coronal Loops
We present observations of a failed eruption of a magnetic flux rope recorded during the M6.2 flare of 14 July 2004. The observations were mainly made with TRACE 171 Å and 1600 Å filters. The flare
Evolving Active Region Loops Observed with the Transition Region and Coronal Explorer. I. Observations
Observations made with TRACE have detected a class of persistent active region loops that have flat 195/171 A filter ratios. The intensity of these loops implies a density that is as much as 3 orders
Combined STEREO/RHESSI Study of Coronal Mass Ejection Acceleration and Particle Acceleration in Solar Flares
Using the potential of two unprecedented missions, Solar Terrestrial Relations Observatory (STEREO) and Reuven Ramaty High-Energy Solar Spectroscopic Imager (RHESSI), we study three well-observed
