Observation and photography

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 total 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 6m 23s. 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.

Longest total solar eclipse over land between 1991 and 2114

Historical significance

The August 2 2027 total solar eclipse delivers 6 minutes 23 seconds of totality near Luxor, Egypt — the longest totality over any land area between the July 11 1991 Hawaii/Mexico eclipse (6m 53s) and the Mediterranean-crossing eclipse of July 16 2186 (the longest of the millennium, projected at over 7 minutes). For human-scale planning, this is the longest land-totality of the 21st century.

Comparison to other eclipses

Compared to the August 12 2026 European eclipse (2m 18s), this 2027 event delivers nearly three times the totality duration. The Spanish coast sees totality just under 5 minutes, Tangier ~4m 49s, Luxor 6m 23s, Mecca and Jeddah ~5m 30s — a once-in-a-lifetime sequence for the Mediterranean and the Arabian peninsula.

Astrophotography context

Peak occurs at 10:08 UTC with the Sun nearly overhead for the Egyptian and Saudi segments — sun altitude is roughly 80-83 degrees, giving the highest-Sun totality of any modern eclipse. The thermal stability of upper-tropospheric haze in midday-August Egypt makes for unusually steady seeing, ideal for narrowband corona imaging. Tripod planning needs to account for shadow bands at low Sun angle being absent — instead expect crisp Baily's beads and the chromosphere prominently visible at second/third contact.

Religious and cultural context

Totality passes directly over Mecca during the Hajj season window (the eclipse falls between Dhu al-Hijjah and Muharram in the 1449 AH calendar). Salat al-Kusuf (the eclipse prayer) is part of Islamic tradition, and this event has been the subject of substantial advance planning by Saudi religious and astronomical authorities.

Frequently asked questions

Where will the total solar eclipse of 2027-08-02 be visible?
The path of totality crosses Spain, Morocco, Algeria, Libya, Egypt, Sudan, Saudi Arabia, Yemen, Somalia. Partial phases are visible from Spain, Morocco, Algeria, Tunisia, Libya, Egypt, and 5 more.
What time will the 2027-08-02 total solar eclipse reach greatest eclipse?
Greatest eclipse occurs at 10:07 UTC on 2027-08-02 (Coordinated Universal Time). To convert to local time for your city, the conversion uses the IANA timezone for that locale — the WorldClockTools eclipse-calendar page surfaces the conversion automatically for any of the listed cities.
How long will totality last during the 2027-08-02 eclipse?
Maximum totality on the central line lasts 6m 23s. Observers off the central line see shorter durations; NASA's interactive map gives the local figure for any coordinates.
When is the next solar eclipse after the 2027-08-02 total solar eclipse?
The next solar eclipse after 2027-08-02 is the annular solar eclipse on 2028-01-26 (15:08 UTC). It will be visible from ecuador, peru, brazil, french guiana, suriname, portugal (south + madeira), morocco, southern spain.
Do I need eclipse glasses to watch the 2027-08-02 total solar eclipse?
Yes — for any solar eclipse (partial, annular, or total), looking directly at the Sun without ISO 12312-2 certified solar viewing glasses or an equivalent solar filter is unsafe and can cause permanent retinal damage. During totality only — the brief window when the Moon completely covers the Sun on the central line — it is safe to look at the eclipsed Sun with the naked eye, but glasses MUST go back on the moment Baily's beads reappear.
What is the Saros series for the 2027-08-02 total solar eclipse?
Total Solar Eclipse of 2027-08-02 is member 39 of 71 of NASA Saros series 136. Each Saros series produces an eclipse every 18 years 11 days, with successive members shifted roughly 120 degrees west in longitude. Saros series typically span 12 to 15 centuries and contain 70 to 80 eclipses each.

Eclipse data depth

What the total solar eclipse entry signals

A compact read of the NASA catalog row: Saros context, magnitude / obscuration math, path geometry, and the city / country cross-references that pair total solar eclipse with WorldClockTools local-clock pages.

Saros series context

Total Solar Eclipse 2027-08-02 is member 39 of 71 of NASA Saros series 136. Each Saros member repeats roughly every 18 years 11 days, shifted ~120 degrees west, so adjacent members in the same series land on different continents.

Magnitude and obscuration

Magnitude is 1.079 (NASA convention: fraction of Sun diameter eclipsed), and the Sun's area is obscured by 100.0%. Magnitude is the diameter ratio; obscuration is the area ratio — both come from the same NASA prediction.

Duration on the central line

Maximum totality / annularity duration is 6m 23s on the central line. Off-central observers see shorter duration; precise local duration is on NASA's interactive map.

Path and visibility footprint

The central path crosses spain, morocco, algeria, libya, egypt, sudan, saudi arabia, yemen, and somalia. Partial phases reach a wider 11-country zone in the current catalog cut.

City cross-references

Cross-referenced cities in the WorldClockTools catalog that fall in the path or partial band: Tangier, Cairo, Makkah, Jeddah, and Madrid. Each city has its own clock page; pairing the eclipse time with the local clock gives the immediate local-time answer.

Gamma and geometry

Gamma is 0.1421 — the lateral distance of the Moon's shadow axis from Earth's center at greatest eclipse, in Earth-radii. |gamma| < 1.0 places the shadow axis on the Earth disc — a central eclipse with a true path of totality or annularity.

What is notable

The longest total solar eclipse over land between 1991 and 2114 — 6 minutes 23 seconds of totality near Luxor. Saros 136 currently produces the longest totalities of any active solar Saros.
