Coronal Hole 2022 10/+4 G2 - a Direct Hit?

[Drax Spacex]

G2 storming currently due to the CH HSS from the transequatorial coronal hole assigned number 10 by SWPC.  We talk about direct hits and glancing blows from CMEs, but could this be considered a direct hit from a coronal hole?  It seems to be the case!

Lol it surprised a few punters, maybe there was a little something else embedded in the solar wind? Like a golf ball? (JOKE)

Also there was a very slow moving CME a few days ago but I didn't see the modelling for this not sure if this contributed to CH effects.

I do wonder if the square shape of this CH, considering the well-defined N-S edge along the western side of the CH, gave rise to a stronger, broader, more abrupt CIR.

Well, I actually don’t see any CIR. When you look at density, the prevailing characteristic of CIRs, there is no large spike as would be associated with a CIR, and certainly not a strong one

I heard it was an unexpected CHHSS, without mention of Co-rotating Interaction Region at this juncture, just south pointing magnetic fields. It has subsided to G1 just now.
