As written here:
Another oddity of nature is that solar eclipses and lunar eclipses tend to come in pairs – a solar eclipse always takes place about two weeks before or after a lunar eclipse.
And here:
Rules of Eclipses (Solar and Lunar) ... Eclipses tend to go in pairs or threes : solar-lunar-solar. Lunar eclipse always preceeded by or followed by a solar eclipse (two weeks between them)
So, seems like a totally common thing.
P.S. The previous pair was first lunar on Oct 8, 2014, and then solar on Oct 23rd.
