An annular solar eclipse occurred at the Moon's descending node of orbit on Friday, April 8, 1921,[1] with a magnitude of 0.9753.

[2] Annularity was visible from northern Scotland, northwestern tip of Norway, and islands in the Arctic Ocean in Russian SFSR.

A partial eclipse was visible for parts of North Africa, Europe, Central Asia, and the Russian SFSR.

This eclipse is a part of Saros series 118, repeating every 18 years, 11 days, and containing 72 events.

[5] The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles.

Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee).
