The supermoon to dwarf all others, or at least the other two this summer, rises Sunday.

The seemingly huge full moon will come up just before sunset at about 7 p.m., about an hour before a "king" astronomical high tide swamps the marshes around the Lowcountry. The perigee moon is apparently larger than normal because it is close to earth in its orbit.

This one will be about as close as it gets - closer than the perigee moon that rose in July or the one that rises Sept. 9.
