I have done "number crunching" of KP indexes for the last 23-ish years because solar peak cycle lasts 11-ish years and I added an extra year just be sure....
The Friday event was KP above 8 and reached 9 at certain points, so we'd need that level of reading to see what we saw I think.
I filtered for all readings of above or equal to 8 (not a huge lot)
Times it reached 9:
October/November 2003, May 2024
Times it reached high 8s:
November 2001, November 2003, November 2004
Times it hit 8 and low 8s:
May 2003, July 2004, May 2005, September 2017, March/April 2023
There's been a few "momentary reads" of low 8s in 2006/12/15/24 but I wouldn't count these. It might have hit 8 at one point during the day and if there's only the one reading of it on a certain day could have been easily missed it in the UK I think (from aurora watching perspective).
Been an interesting exercise. Basically it was more than 20 years ago we saw this level of activity.
See ya all in 20 years time

or may be in October/November is 2004 repeats
