A bright full moon rose on Wednesday night over Portugal's capital Lisbon, marking the third and final 'supermoon' phenomenon of 2019. If skies are clear, the full moon appears up to 14 percent bigger and 30 percent brighter than usual, according to NASA.
A supermoon occurs when the timing of a full moon overlaps with the point in the moon's 28-day orbit that is closest to Earth. The next supermoon is not set to rise until spring 2020, according to weather reports.
