Coronal hole faces Earth
It's that time of the solar cycle again where coronal holes become more apparent at lower latitudes! Less than a week ago we already had a similar coronal hole facing our planet. The solar wind stream from that coronal hole caused active geomagnetic conditions on Tuesday. Right now we have yet another northward extension of the southern hemisphere polar coronal hole facing our planet today.
