(CNN/KABC) - The summer of supermoons kicks off this weekend.
NASA says this summer's full moons will all be supermoons.
The first will be visible Friday night and then again on Saturday night.
The scientific term for the phenomenon is "perigee moon", which makes the moon appear larger and brighter.
It will also happen again Aug. 10 and Sept. 9.
Experts say the one on Aug.10 will likely be the brightest.
However, scientists stress that sometimes it's hard to tell the difference between a supermoon and a regular full moon, as clouds and haze can mask a difference in brightness.
