Solar Saros 138 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series. This eclipse series began in AD 1427 with a partial eclipse at the southern edge of the Earth's shadow when the Moon was close to its descending node. Each successive Saros cycle, the Moon's orbital path is shifted northward with respect to the Earth's shadow, with the first total eclipse occurring in 1950.
