While some tech people behind the scenes are overwhelmed and scrambling to keep all kinds of electrical infrastructures up and running, or at least safe until the solar storm blast passes.
Plus they were expecting it, have been low-key preparing for weeks or months - knowing there's a solar maximum - then much more actively a few days and hours before the event arrived, thanks to solar weather satellite forecasts being a reliable thing now.
It doesn't do anything the affects us other than the pretty colours the vast majority of the time, that's the actual reason. The experience is just the colours, there's nothing to worry about.
Radiation does not by definition make things it impacts radioactive, and most of the lingering effects that we associate with radiation have to do with radioactive particles that are left behind by the atmosphere. Since there is no particulate matter traveling between the sun and Mars (photons not withstanding), the surface of Mars would not be expected to acquire radioactive properties from an acute solar radiation event like this one. However, an entity on the surface of Mars would be exposed to radiation from the Sun, much more so than an entity on/near earth and it's magnetosphere (Mars' thin atmosphere and distance from the sun probably helps reduce that disparity relative to something in say low earth orbit, but I don't think it fully equalizes or shifts the scales). I am not an astrophysicist, so there's at least a 20% chance I got part of that wrong.
Just adding to this, some foods are actually irradiated for preservation purposes. If you’ve purchased premium ____, you may have had a bit of irradiated food. Given that widespread dna breakdown hasn’t occurred across the entire planet, irradiated matter is usually harmless.
