Annular path begins in North Africa (Algeria, Tunisia, Libya), crosses the Mediterranean (clipping Malta and southern Greece), Black Sea (Bulgaria, Turkey, Ukraine), then sweeps through European Russia, Kazakhstan, Siberia, and ends in northern Japan (Hokkaido). Major cities under the partial phase: Athens, Istanbul, Moscow, Beijing, Seoul, Tokyo.
Last annular eclipse of the 2020s decade — the path crosses three continents from Algeria to Hokkaido, with major partial-zone coverage of central Asia and the western Pacific.

Every phase of a solar eclipse outside of totality requires ISO 12312-2 certified solar viewing glasses or an equivalent solar filter on every optical instrument (telescope, binoculars, camera lens). The same standard applies to annular solar eclipses. Glasses can come off only during the brief totality window on the central path; they must go back on the instant Baily's beads reappear at third contact.
Central-line duration is 5m 21s. A typical imaging plan brackets exposures from ~1/1000s for the chromosphere and Baily's beads down to ~2s for the outer corona, fired in a programmable sequence so the observer can watch with the naked eye for at least the middle third of totality.
Local sun altitude, the path crossing time of day, and recent weather climatology drive site selection. NASA's interactive eclipse map (linked below) gives the exact altitude and time for any coordinates on the path.
Editorial dossier
Historical significance
The June 1 2030 annular solar eclipse traces an exceptionally long land path — from Algeria, Tunisia, Libya and Malta, across Greece, Turkey and Russia, into Kazakhstan, northeastern China and northern Japan. It is the first central solar eclipse to cross Athens, Istanbul and Hokkaido on a single arc in the modern era, and the first annular eclipse to pass over Istanbul / Constantinople since the 16th century. It is member 59 of 73 in Solar Saros 128, a series that began on August 29 984 AD and that now sits in its mature annular phase.
Comparison to other eclipses
For Greece and Turkey, this is the most accessible central solar eclipse of the 2020s and 2030s — and follows the same Saros family as the May 20 2012 annular that crossed the western U.S. and Japan. Russia and Kazakhstan, meanwhile, see this as a curtain-raiser to the August 12 2026 totality that recently crossed the Atlantic — but here the Sun rings, rather than vanishes. The next annular to cross continental Europe along a similar diagonal is not until 2093.
Astrophotography context
Greatest eclipse occurs at 06:29 UTC, with annularity lasting up to 5 minutes 21 seconds and a maximum path width of 250 km (160 mi). The path crosses major cities in striking morning light: Athens sees annularity around 07:58 local time, Istanbul around 08:04 local, with the Sun at 15-25 degrees altitude. Russian and Kazakh observers get higher-Sun annularity (40-60 degrees) in mid-morning. Sapporo on Hokkaido sees a low-Sun annular near 16:57 local time. The combination of iconic urban skylines and a comparatively short ring phase makes this one of the most cinematic eclipses of the decade. Use a certified solar filter throughout — annularity is never safe to view filterless — and bracket 1/2000s to 1/30s through ND5 to capture limb structure across the 5-minute window.
