February 2017 lunar eclipse

A penumbral lunar eclipse took place at the Moon’s ascending node on February 11, 2017, the first of two lunar eclipses in 2017. It was not quite a total penumbral lunar eclipse. It occurred the same day as comet 45P/Honda–Mrkos–Pajdušáková made a close approach to Earth (0.08318 AU). It also occurred on the Lantern Festival, the first since February 9, 2009. Occurring only 4.4 days after perigee (Perigee on February 6, 2017), the moon's apparent diameter was larger.
