Didn’t seem to directly answer the question. A so-called “supermoon” is when perigee and full moon occur close to the same time. My question was whether this is the closest the moon will be since 1948, the closest it has been to earth at perigee since 1948.
In 1948 these circumstances obtained:
Perigee: Jan 26 11:17 356462 km
Full: Jan 26 7:12
In 2016:
Perigee: Nov 14 11:24 356511 km
Full: Nov 14 13:54
