I am sure that the term perigee does not correspond and must be changed for the apogee, in addition, the moon phase changed three hours after the apogee
The U.S. Naval Observatory's MICA software shows lunar perigee (closest to earth) on May 6, 2020, at 03:03 UT1 and full moon on May 7, 2020, at 10:45 UT1. That's a difference of 31 hr 42 min, for which the APOD's "within about 32 hours of perigee" is an entirely satisfactory approximation.
