When the solar wind is sprayed on the earth, a huge "coronal hole" appears on the surface of the sun: 800000 kilometers wide

CTOnews.com, Dec. 6 (Xinhua)-- NASA astronomers, through the Solar Dynamics Observatory (SDO), observed that the sun is "opening" a huge, scary hole and ejecting solar wind directly at the earth.

Astronomers observed a huge hole in the solar atmosphere (Sun atmosphere) on December 2. Astronomers named it the Coronal Hole (coronal hole), which reached 497000 miles in size in just 24 hours. (CTOnews.com Note: about 799843.97 km).

Scientists say the temporary gap is wider than 60 Earths and exceeds previously observed solar cycle records. CTOnews.com note: since December 4, this "coronal hole" has been pointing at Earth, spewing rapid radiation / solar wind.

Astronomers had predicted that the coronal hole would trigger a moderate G2 geomagnetic storm, but it turned out to be weaker than expected, causing only a weak G1 geomagnetic storm.
