Failed filament eruption


GONG observations of active region 14246 show a spectacular but failed eruption of the chromospheric filament. Dark material appears to be erupting following untwisting magnetic field lines, but then expands and falls back to the chromosphere. Observations were taken by GONG/Udaipur (India) on 14 October 2025 between 02:01 UT and 11:33 UT.
