Northern Lights Now – A pair of coronal holes are increasing the chances for aurora early this season. These coronal holes will bring high speed solar wind and the potential for aurora. Stay tuned
The two coronal holes in this image will give earth a 1-2 punch between Sept 6 and 13. Both holes (the dark areas in the image) are located close to the equator which means their wind streams are likely to impact Earth
So far, based on STEREO-A data, it looks like the second storm may pack a stronger punch.
