This is about the best photo I can get. I did NOT bring an appropriate camera with me to Europe. But to the eye, it's a faint, hazy red-orange. Thank-you refraction (Snell's Law) and Rayleigh Scattering for this stunning spectacle! https://twitter.com/drsekula/status/1022943924724412416/photo/1 https://chirp.cooleysekula.net/attachment/51460
