Supermoon vs minimoon

Angular comparison of super and mini full moon as seen on 14th of November 2016 and 10th of June 2017. Difference is not really observable by naked eye.
Both images were taken with the same equipment (Nikon D500 and Tamron 70-300@300m) at two different times. Composite of both images clearly shows us the change in apparent angular size of the moon that is caused by the difference of its distance from Earth at perigee and apogee. The change in apparent size is caused by the Moon’s elliptic orbit around Earth and it amounts to distance difference of approximately 40,000km between both full moon events.
