A brand new report warned a couple of potential geomagnetic storm tomorrow, August 18. Two CMEs that erupted on August 14 and 15 are set to hit Earth collectively on August 18.
On August 14, a darkish plasma eruption round sunspot AR3076 hurled one CME towards Earth. Touring quicker than 600 km/s (1.3 million mph), the plume tore via the solar’s outer ambiance, making a coronal mass ejection (CME).
Likewise, on August 15, an exploding magnetic filament launched one other CME proper behind it.
Based on the prediction from the NOAA mannequin, each CMEs may arrive collectively on Earth on August 18. And this might be the “Cannibal CME” occasion.
CME cannibalization happens when the solar launches two eruptions inside a brief time frame, with the second of the 2 being extra energetic and due to this fact quicker than the primary.
As reported in spaceweather.com, “The second CME would possibly overtake and gobble up the primary, making a mishmash of the 2.”
“NOAA forecasters have upgraded their geomagnetic storm watch from class G2 (reasonable) to class G3 (sturdy) in response to fashions that recommend a number of CME impacts on August 18. Throughout such storms, naked-eye auroras can descend into the USA as far south as Illinois and Oregon (geomagnetic latitude 50 levels). Cameras with delicate night-sky settings might report auroras even farther south than that.”
