Powerful double solar eruption beyond the east limb

A powerful double solar flare eruption took place beyond the Sun’s east limb early October 18, 2017. The responsible region is now rotating into Earth view and will be visible in a couple of days.

By The Watchers

The eruption was associated with a Type II (estimated velocity 1 443 km/s) and Type IV radio sweeps indicating a strong Coronal Mass Ejection (CME) was associated with the event. In fact, there were two associated CMEs, first visible in coronagraph imagery at 05:48 UTC.

None of these CMEs are Earth-affected, but the responsible region is now rotating into Earth view and there is a possibility of an increased solar activity over the next 14 – 16 days as this region rotates through.
