    The skies of Lhasa, capital of Tibet, were graced by a solar halo on Monday, May 5.

    This optical phenomenon occurs when sunlight bends as it passes through the ice crystals in a high, thin layer of cloud called cirrostratus. It is also known as a 22 degree halo, because this is the angle the light is refracted by these tiny crystals.

    Solar halos are often seen in Tibet. Check out more photos of these beautiful sun circles here.
