No warnings at NOAA Space Weather Prediction Center.[1]<p>No warnings on PJM grid dashboard.<p>Probably not going to be a problem.<p>[1] <a href="https:&#x2F;&#x2F;www.swpc.noaa.gov&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.swpc.noaa.gov&#x2F;</a>

&gt; The solar flare emanated from the sunspot group AR3842, which has made headlines before. On Oct. 1, the same sunspot region fired off a powerful X7.1 solar flare and unleashed a coronal mass ejection (CME) — a plume of plasma and magnetic field — which is currently barreling toward Earth. That incoming CME is expected to hit Earth between Oct. 3 and Oct. 5, possibly triggering widespread auroras.<p>I actually just saw an aurora for the first time in my life a few months ago in Oregon, where they&#x27;re hardly ever visible. It was quite a sight. Maybe I&#x27;ll get to see them again.

Does this have any effect on the human body? Is this exposure measurably damaging for people?

Prediction: Absolutely nothing significant will happen here.
