*EARTHQUAKE ALERT* LARGE CORONAL HOLE TURNING TOWARD EARTH

 

 Ajoutée le 18 déc. 2016 

A BIG CORONAL HOLE TURNS TOWARD EARTH: For the third month in a row, a large hole in the sun's atmosphere is turning toward Earth. NASA's Solar Dynamics Observatory photographed the yawning structure on Dec. 16th. This is the same coronal hole that lashed Earth's magnetosphere with solar wind on Oct. 25-28 and again on Nov. 23-26. It is spinning around with the sun, strobing Earth lighthouse-style every ~27 days. The last two times we experienced its solar wind, intermittant G1-class geomagnetic storms and bright auroras were observed in the Arctic. A repeat performance is likely when the solar wind returns on Dec. 20-22.
