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.
För att vara tillgängliga vid stora norrskensutbrott måsta vi ha kraftiga servrar som kan hantera alla besökare. Donera och stöd vårt projekt, så att vi kan finnas online även under stora stormar!
