Interplanetary shocks preceded by solar filament eruptions

Journal of Geophysical Research, 1986
We discuss the solar and interplanetary characteristics of six interplanetary shock and energetic particle events associated with the eruptions of solar filaments lying outside active regions. The events are characterized by the familiar double‐ribbon Hα brightenings observed with large flares, but only very weak soft X ray and microwave bursts.

Low-energy particle events and solar filament eruptions

Advances in Space Research, 1986
Over the period from August 1978 to October 1982, several large low-energy (E < 1.6 Mev) proton events associated with interplanetary travelling disturbances observed at 1 AU by ISEE-3, appeared not to be triggered by solar flares. Six of them can be associated with filament eruptions as the source of the disturbances.

Eruption of a Bifurcated Solar Filament

Solar Physics, 2013
We study the partial eruption of a solar filament observed by the Solar Dynamics Observatory (SDO) and the Solar TErrestrial RElations Observatory-Ahead (STEREO-A) spacecraft on 9 May 2012. This filament was located in Active Region NOAA 11475 and consisted of two distinct branches, separated in height above the active region’s primary polarity ...

Failed Eruptions of Solar Filaments

Astronomy Reports, 2020
Solar filaments (prominences), which suddenly and swiftly ascend, i.e., become eruptive, sometimes decelerate and stop at comparatively low altitudes. Causes of failed eruptions generally remain uncertain. The present study analyzes two eruptive phenomena with very similar initial geometries and configurations of external magnetic fields; one of these ...

The two types of flare-associated filament eruptions [PDF]

open access: yesSolar Physics, 1986
Using years of high resolution solar footage obtained at Big Bear Solar Observatory flare associated filament eruptions were studied. In addition to the classical type eruption consisting of expansion and breakup, evidence was found of another type where
