Apparently there are 100 of these per 11-year solar cycle.

Seems that there are much more than 100 flares each cycle: https://hesperia.gsfc.nasa.gov/hessidata/dbase/hessi_flare_l...

It also seems that flares above X2.2 are quite rare. There have been only 10 of those since 2008: https://en.wikipedia.org/wiki/Solar_cycle_24#Events

The latest flare, measured at X9.3 is VERY rare: https://www.spaceweatherlive.com/en/solar-activity/top-50-so...

I wouldn't downplay this

That last link is extremely interesting. Just spent some minutes watching the videos of previous record setting flares.

The flares oriented towards Earth are very obvious due to the amount of static after flare ejection. We all exist in a narrow band of of environmental conditions, spooky thinking about how much energy is occasionally hurled towards us. Just a slight lick from Sol and we could be done for.

G4 geomagnetic storms, not flares.
