Google CME or Coronal Mass Ejection and learn all about it.

A coronal hole is something different from a CME. A CME is a solar
flare, giant burst from the sun whike a coronal hole is a relatively
cooler area of the sun (they appear dark in EIT images) that also have a
higher release of particles then other area's from the sun.

A CME generally has more impact on earth (if it was earth bound) then a
CH, as more matter is released.

Things are a bit oversimplified, but HTH


So what sort of impact on radio propagation/reception should one
expect a solar hole to impose?

Does a solar hole result in only increasing the velocity of the solar
wind without the massive increase in particle count that occurs during
a CME event?
