Solar physics: coronal holes & sunspot cycles

[windy miller]

Does anyone know if there is a relationship between corneal holes and the sunspot cycle?
As we move in now towards solar minimum should we expect to see a big decline in corona holes?
I have noticed a lot less sun spots over the last few months but the frequency of coronal holes seems to be unchanged, but this just my unscientific impression
Any real knowledge much appreciated

hi there

here's a paper that will shed some light on the subject

Thank you for posting this , I had a brief read but it appears to be taking about the location of coronal holes during the solar cycle, not so much the frequency. or did i miss that?

true, it didn't really get into that much ... info seems to be sparse and ones that hinted with the info are behind paywalls

I will keep an eye out for anything more substantial
