Not entirely sure but I think the planet just got hit by something. I am pretty sure that I should never have to see a UV index of 15. I was under the impression that my equipment was malfunctioning until I looked at other local locations and then a location from a couple friends, one in Ohio and one in Florida. The trends all looks the same. According to spaceweather.com it looks like a coronal mass ejection should hit but it seems a little early I am not sure that it is the same type of radiation.
Looking at the data from my weather stations. I wonder what SPF I would need for this?
Here you can see the timing of the event along with solar radiation as well as UV.
Furthermore my Friend Ed in Florida and another location in Ohio showed the same spike. Something was clearly going on.
