          * Constellation shown for northen hemisphere skies. For the southern hemisphere, constellations appear rotated 180 degrees (upside-down and left-right reversed) from what is shown. Remember that seasons are reversed too - summer in northern latitudes is winter in southern latitudes.

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