This subcat is intended for pictures of all ice-crystal haloes visible below the horizon (i.e. seen from above):
Subsun (a bright point below the Sun), Subparhelia (appearing as sundogs to the Subsun, although they are not!), Sub-parhelic circle (symmetrical to the Parhelic circle), and several Antisolar arcs.
Some usually above-horizon arcs may also fit here as they appear below the horizon when the Sun is low, such as the Lower tangent arc.
