Then we have a difference of opinion on ‘routine’: according to the chart linked at post 15 above, this magnitude occurs several times per solar cycle (11-ish years). Even accepting your ‘over 12 years’ figure, that’s still roughly once per solar cycle. And even t that, it’s not a Babylon-desolation-like event.
S5 level? Then yeah, I’d be a lot more concerned. S3 is stout, but it’s not gonna invoke Revelations 18.
