I was very lucky to spot this optical phenomenon as well as photographing a vertical rainbow two weeks back, this one which is the second I have ever witnessed the other being on the summit of Cadir Idris, however this was one photographed in the Breidden Hills on the summit of Moel y Golfa with a summit of 403 metres (1,322 ft), as Solar glory and Spectre of the Brocken are always witnessed on hill or mountain summits and have been witnessed from aircraft.
A glory is an optical phenomenon that resembles an iconic saints halo about the shadow of the observer's head. The effect is believed to happen due to classical wave tunnelling,, when light nearby the droplet tunnels through air inside the droplet and, in the case of glory, is emitted backwards due to resonance effects.
A Brocken spectre is the apparently enormous and magnified shadow of an observer, cast upon the upper surfaces of clouds opposite the sun. The phenomenon can appear on any misty mountainside
