New coronal hole in the solar atmosphere, alert for aurora possibilities
Just saw a notice on Spaceweather.com
that a large hole in the solar atmosphere is turning toward Earth. It
is expected to blast us with a very high-velocity (700 km/second!!)
stream of solar wind, arriving on June 16th, and possibly sparking
G1-class geomagnetic storms. Could be interesting auroras particularly
in the southern hemisphere because of
the autumn darkness.
