Coronal hole, SpaceWeatherLive alerts
It's that time again. We have yet another coronal hole facing Earth right now. A large northward extension of the southern hemisphere polar coronal hole that stretches all the way to the solar equator, is now in an earth-facing position. An enhanced solar wind stream could arrive on April 12 or April 13 and minor G1 geomagnetic storm conditions are possible when the solar wind stream arrives. Our header image shows this large coronal hole as captured by NASA's Solar Dynamics Observatory (SDO) in the 211 Ångström wavelength.
