To some it's a pretty novely, to others the harbinger of the apocalypse.
We're talking, of course, about the red sun seen around the UK today (October 16). The fact that we've got sun at all in mid-November is remarkable enough; the fact that it's a pinkish-orange is off-the-scale bonkers.
It's actually got a prety normal explanation, however. Storm Ophelia, the ex-hurricane which is currently battering Ireland, has dragged dust and tropical air from the Sahara Desert on its journey to the UK.
As as a result, wavelengths of blue light become scattered, making the sun appear red and consquently, turning the clouds the colour we've seen this afternoon.
It has an eerie, spectral beauty, and Twitter users have been reacting accordingly - with portents of doom, commentary, and memes.
