Coronal holes

More good news for high latitude sky watchers: the show will go on! Two more coronal holes can be seen on SDO imagery right now. One of those coronal holes is a large coronal hole on the Sun's northern hemisphere and it is facing Earth right now. Another high speed solar wind stream could hit our planet within the next 48 to 72 hours and could very well cause more periods where we reach the minor G1 geomagnetic storm threshold.
