"Super New Moon" is apparently an astrology term for when it is a new moon and the moon is at the perigee of it's orbit in relation to Earth. There is a calculator here: www.fourmilab.ch/earthview/pacalc.html (This is not an astrology website. I also do not claim that calculator is correct, it was just the first one I found)

In May the perigee was 1day 15 hours after the new moon. In June it was 15 hours after the new moon. July it was 6 hours before and in August it will 1 day five hours before the new moon. So whether it was a super new moon or not depends on the range of the orbit you consider the perigee. It looks like the next time they perigee point and the new moon will coincide within in a few minutes of each other is January 21st, 2023 (3 minute spread). The occurrence of several months in a row when the perigee point and the new moon are within a day or so of each other seems to be fairly common and happens every year I believe. IIRC, the phase cycle is about 27.5 days long and the orbital cycle is just over 29 days.
