CH 2nd December

[Adrian Kobyłecki]

Will any coronal hole experts comment on what is currently happening? The parameters have just gone up, but I have no idea what will happen next. Someone please explain to me

[tniickck]

the solar wind speed was supposed to be ≈700 km/s, but it is now about 550. The CH is weaker than we all expected

[Jesterface23]

A CH HSS entered, then there are influences from a filament flare CME (somehow got it mixed up at some point) eruption that arrived early this morning UTC.

Is there anywhere to see real time KP? As I understand we only get forecast, and the real data gets published later, I believe based out of a site in Germany?

Here's one predicted Kp, along with preliminary Kp values from NOAA and GFZ.

Here is a link to the live Kiruna data from Sweden

Cool.  Never knew before!  68n no wonder their Magnetometer is usually among the quickest and wildest in any event!

Keep in mind that’s local K and not Kp!

Corona hole wind appears to increase to 650 kilometers per second

Wydaje się, że prędkość wiatru w dziurze koronowej wzrasta do 650 kilometrów na sekundę 

this is probably the final phase and within a few hours the wind speed will decrease

When the IMF Bt dropped, that would be around when the CH HSS fully kicked in. It was a decent sized CH, so it still may last a day or two.
