Photographic auroras:
Photographic auroras (visible to the camera, but not the eye) descended to mid-latitudes. “Today brought yet another photographic aurora here in the southeast of England at latitude +51N,” reports Jamie McBean of Herne Bay, Kent, UK. “This is my 14th aurora on camera this year, which I find incredible considering I had never believed I could get anything from here a mere year ago!” [Spaceweather.com]
Some fascinating pics, as usual.
