From Kate Goldstone, Torrington, Devon, UK
Thanks to you, I have solved a mystery. One night last month – sadly I didn't make a note of the date – my husband and I went for an evening walk in the countryside around our north Devon home, where there's very little light pollution.
There was no moon, but the sky was extremely bright and structures cast dramatic shadows. I now assume we experienced a “bright night”: spectacular, and very strange indeed (23/30 December 2017, p 63).
