            * For southern latitudes, flip the season listed. For example, if a constellation is listed as best viewed in the summer in the month of July, in the southern hemisphere the constellation would be best viewed in the winter in January and would be upside-down.

            ** Circumpolar constellations are visible year-round in the hemisphere listed (and not at all in the opposite).
