They're sun halos, caused by sunlight shining through ice crystals. Atmospheric optics expert Les Cowley explains:
"These two 'V' shaped halos, one rare and one common, change shape dramatically as the sun climbs," he says. "Near sunrise or sunset is the only time to catch them like this. The lower 'V' is an upper tangent arc from horizontal hexagonal prisms of ice.
The upper one is a rare sunvex Parry arc from similar crystals that - strangely - are fixed so that two prism faces are always horizontal. In the full-sized image, we also see just a trace of a 22o halo and stretching upwards from the sun a sun pillar."
