Filament Eruption on 14 Jan 2016

Filament Eruption on 14 Jan 2016
published: Friday, January 22, 2016 06:56 UTC

A filament eruption was observed taking off just south of center disk late on 14 Jan 2016.  The resulting partial-halo CME was observed in coronagraph imagery (displayed image).  Subsequent WSA-ENLIL modelling of the events shows a weak glancing blow possible early on 19 January (UTC day).  Only active periods (Less than G1-Minor) are expected with the arrival of the CME.
