I couldn't really see anything from just outside Truro, although the sky seemed a bit brighter I wasn't sure whether that was just a bit of mist illuminated by artificial lights. I think the peak of the storm was slightly earlier, when it was partly cloudy where I was.
Have a look at the link below to see pictures from other people who did see it.
