There's at least one behind 2995 too.

How unusual are these clusters? Also, they seem a bit to the north. I assume they would be more threatening if they were right on the equator?

It's not terribly unusual to see clusters like this in the +/- ~3 years surrounding solar maximum. And yes, the progression of sunspot latitude over the solar cycle progresses from higher latitudes to nearer the equator

And another yes; Sunspots are generally more geoeffective the closer they are to the equator. But mostly, it's a matter of luck. 1) Whether a Carrington-level event is produced at all, and 2) Whether it is Earth directed.

As for assigning a probability to the likelihood of another Carrington CME hitting Earth, it seems like a fool's errand, with one datapoint over 150 years. We don't even know what the actual plasma conditions were out there, just the Earth's response at the time, and only a vague picture of that, to boot. I'd be surprised if there wasn't an order of magnitude difference between different estimates, so I guess I find some comfort in the uncertainty. Let's pray for the 1% estimate. Of course, it's only a matter of time. Hopefully the sun holds off until this era of social turmoil resolves itself.

Maybe another Carrington event will teach us all that what was most important to us was in front of us all along and there will be peace on Earth.

4/20 was yesterday, but you're still high

edit: nihilism plays way better in person, srry

Interesting. Pete Riley suggested a 12% chance of Carrington class event between 2012 and 2022

https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2011SW000734

Whereas another group says around 1% between 2019 and 2029

https://www.nature.com/articles/s41598-019-38918-8

I'm going to take the average and say 6%.

TIL that near solar maxima, the Sun produces about three CMEs every day, whereas near solar minima, there is about one CME every five days.
