Not a solar flare but a coronal mass ejection. And while the subsequent G5 geomagnetic storm can do damage to various technological systems, it shouldn't be anything too bad.
The extreme ultraviolet and x-ray radiation from solar flares is absorbed by the daylight side of Earth's upper atmosphere, in particular the ionosphere, and does not reach the surface.
You should know that this wasn't a solar flare, but a coronal mass ejection. Look that up instead. No, it's nothing too bad either. The one in 1859 was a big one and some people got electrocuted at telegraph stations, but this ain't like that.
