URL: IS A 'CANNIBAL CME' COMING? |
|
Since Feb. 7th, the sun has hurled multiple CMEs into space. A handful of them might hit Earth this week. A new NOAA forecast model shows at least three solar storm clouds approaching for strikes on Feb. 13th:
The closely-spaced arrival of these three CMEs could spark G1 (Minor) to G2-class (Moderate) geomagnetic storms with high-latitude auroras in northern Europe, Canada, and northern-tier US states from Maine to Washington.
There's a chance (slim but non-zero) that these CMEs will pile up to form a Cannibal CME. This happens when one fast-moving CME sweeps up slower-moving CMEs in front of it. Cannibal CMEs typically contain strong shocks and enhanced magnetic fields that do a good job sparking geomagnetic storms. If such a pile-up occurs, the combined strike could cause a G3 (Strong) geomagnetic storm with auroras at mid-latitudes.

It's not really cannibalizing it's more like one CME
pushes the other in a pile up...like a snow plow.
Spaceweather.com uses the term in a misnomer type of
fashion for views.
