“There is talk of a super moon whenever the moment of a full moon occurs when the moon is less than 110% of the perigee of the earth of its orbit. In temporal terms, this means that the difference between the moments of a full moon and perigee is less than one day and 8 hours. According to this definition, from Giant moons may occur frequently, but not all of them will have the same apparent size and brightness. See here in this table for the list of giant moons that will occur until 2050. “, Lisbon Astronomical Observatory (OAL).
