This eclipse is the one of four lunar eclipses in a short-lived series at the ascending node of the moon's orbit. The lunar year series repeats after 12 lunations or 354 days (Shifting back about 10 days in sequential years). Because of the date shift, the Earth's shadow will be about 11 degrees west in sequential events.
A penumbral lunar eclipse will take place on March 23, 2018, the first of three lunar eclipses in 2018. Every year, there are at least two lunar eclipses and as many as five, although total lunar eclipses are significantly less common. If one knows the date and time of an eclipse, it is possible to predict the occurrence of other eclipses using an eclipse cycle like the saros.
