The first of two January 2018 full moons fell on the evening of Jan. 2 for the Eastern Hemisphere. This full moon came only 4.5 hours after the moon reached lunar perigee – the moon’s closest point to Earth in its monthly orbit. Thus this full moon presented the closest – and thereby the largest and brightest – supermoon of 2018. Of the 13 full moons and 14 lunar perigees occurring in 2018, this is the closest alignment of full moon and lunar perigee for the year. This close coincidence of full moon and perigee in early January 2018 not only gives us the closest full moon of 2018 but also the closest lunar perigee of 2018. See below to note the nearness in time of this perigee and full moon.
