Filament eruption on 2010 October 21 from three viewpoints
Boris Filippov

TL;DR
This study analyzes a solar filament eruption on October 21, 2010, using multi-viewpoint observations from STEREO, SDO, SOHO, and Kanzelhoehe Observatory, revealing the eruption's magnetic conditions and movement along the neutral surface.
Contribution
It provides a detailed multi-viewpoint analysis of the filament eruption, including magnetic field calculations and eruption dynamics, which enhances understanding of solar eruption mechanisms.
Findings
Eruption occurred when the magnetic decay index exceeded one.
Filament moved along the magnetic neutral surface during eruption.
High-precision magnetic field distribution was calculated near the filament.
Abstract
A filament eruption on 2010 October 21 observed from three different viewpoints by the Solar Terrestrial Relations Observatory (STEREO) and the Solar Dynamic Observatory (SDO) is analyzed with invoking also data from the Solar and Heliospheric Observatory (SOHO) and the Kanzelhoehe Solar Observatory. The position of the filament just before the eruption at the central meridian not far from the center of the solar disk was favorable for photospheric magnetic field measurements in the area below the filament. Because of this, we were able to calculate with high precision the distribution of the coronal potential magnetic field near the filament. We found that the filament began to erupt when it approached the height in the corona where the magnetic field decay index was greater than one. We determined also that during the initial stage of the eruption the filament moved along the magnetic…
