Another major quake the 6th to strike our planet since Saturday afternoon and incredibly the 9th in this area this month as well as including the massive mag 8.0 in Papua New Guinea on the 17th and the mag 7.8 on the 8th, the area is suffering hundreds of aftershocks too.
This is a "coronal hole"--a region in the sun's atmosphere where the magnetic field opens up and allows solar wind to escape. We've actually seen this coronal hole before--at least twice. It is rotating around with the sun, strobing Earth like a lighthouse every ~27 days. The last two times we experienced its solar wind (Oct. 25-28 and Nov. 23-26), G1- and G2-class magnetic storms sparked bright polar auroras. A repeat performance is likely in the week ahead.
