Filament eruption, glancing blow possible on April 15

Filament eruption, glancing blow possible on April 15

An approximate 14 degree solar filament eruption began at 20:25 UTC on April 9, 2017, from the northeast quadrant of the Sun. The event generated a coronal mass ejection (CME) and a glancing blow is possible on April 15.

The CME was first observed in SOHO/LASCO C2 imagery at 01:25 UTC on April 10. The preliminary analysis of available SDO/AIA imagery indicated an unlikely Earth-directed component, but subsequent analysis by forecasters and WSA/Enlil modeling determined a possible glancing blow from the CME. 

The arrival is expected on April 15.

The event can be seen in the videos below, both eruption and the canyon of fire the filament left behind. Additionally, LASCO C2 and C3 movies show the CME on April 10 and a nice looking sundiving comet on April 8.
