A massive coronal hole appeared on July 18th, 2013 near the north pole of the Sun.

Phys.org has a report on this coronal hole and the solar winds that come with it.  This report states, “The holes are important to our understanding of space weather, as they are the source of a high-speed wind of solar particles that streams off the sun some three times faster than the slower wind elsewhere.

According to the report, the cause of coronal holes is “unclear“.

The holes are important to our understanding of , as they are the source of a high-speed wind of that streams off the sun some three times faster than the slower wind elsewhere. While it’s unclear what causes coronal holes, they correlate to areas on the sun where magnetic fields soar up and away, failing to loop back down to the surface, as they do elsewhere.
