Northern Lights Now – A High Speed Stream from a coronal hole, coupled with CMEs from multiple Solar eruptions means there is a good chance for active aurora over the coming days. This is a complex system, but carries many indicators that aurora hunters may be in luck. Stay tuned as NLN continues to provide updates over the coming days. We will get the coverage started with the NLN clock showing the predicted activity over the next three days.
Northern Lights Now – Another CME launched from the Sun and the updated forecast calls for more potential periods of G1 storming on Nov 4.
There have now been three significant flares with associated CMEs across the previous two days. The first two are from Active Region 2887 (the one that produced the X-class flare and storming over Halloween weekend) which is now rotating around the west limb. The third, launched on Nov 2, was from AR 2891 which is currently center disk. This likely means we’ll receive a direct hit.
The CMEs traveling out from these eruptions will likely interact and make for a somewhat complicated forecast. That said, SWPC has updated the Forecast and is now showing a period of Activity late on 11/3 and early on 11/4 then another period of G1 storming later in the Nov 4 period. It is very possible the forecast is conservative given the position of the third eruption. Here is the most recent forecast:
Here is an annotated two day composite of LASCO showing the three eruptions that are responsible for the activity predicted in this forecast.
Northern Lights Now – A complex set of flares from AR 2887 have launched CMEs that mean there is a good chance for Aurora on Nov 4 and Nov 5. SWPC has issued a G1 Geomagnetic Storm watch. These storms we’re complex, and we expect this forecast to be revised.
Here is the projected timeline for solar activity:
Edit: Later, another flare launched from AR2891 from near center disk. The CME launched from this eruption will almost definitely arrive at Earth, and will likely interact with the already launched CME. The forecast will be updated soon.
