Eclipse classifications are from NASA GSFC. On this site, “supermoon” means a full moon with a computed geocentric distance of 360,000 km or less.
Daily Moon Phase, Illumination, and Moonrise
“No moonrise” means no rise occurs during that midnight-to-midnight Eastern calendar date at the New York City observer location; it does not mean the moon never rises.
