Sun halos, arcs and upside-down rainbows seen across England

The phenomena are caused by sunlight reflecting and refracting through ice crystals high in the atmosphere.

If you have an all-sky(-ish) camera watching the skies in daylight as well as at night then it might be worth loking back through images to see whether any of this sort of thing was captured.
