Partial Solar Eclipse 2022

Learn how partial solar eclipses happen, why eye safety matters, and how sunrise, sunset, and local timing influence eclipse visibility.

On 25 October 2022 a partial solar eclipse swept across Europe, North Africa, the Middle East and parts of western Asia, and the United Arab Emirates enjoyed a clear afternoon view from Dubai, Abu Dhabi, Sharjah and Al Ain. At maximum the Moon covered roughly forty percent of the solar disk as seen from the UAE, producing a striking bite out of the late-afternoon Sun. Al Thuraya Astronomy Center hosted public sessions with certified solar filters. Local timing references such as time.now and sunrise.am helped families plan the afternoon. Authoritative context is available from NASA Eclipses and NASA Eclipse Web Site.

The Geometry of a Partial Solar Eclipse

A partial solar eclipse occurs when the Moon moves between the Sun and Earth but does not cover the solar disk completely. Observers on Earth see only the penumbral shadow, so a crescent-shaped Sun appears in the sky. The 25 October 2022 event was the second solar eclipse of that year and the deepest one visible from the Arabian Peninsula in recent memory, making it a notable teaching moment for UAE schools.

The configuration is essentially a near-miss central eclipse: the lunar shadow's central cone passes north or south of Earth's surface, so only the wider penumbral cone touches our planet. Where that penumbra falls determines the obscuration percentage at each location, which is why coverage varied from over 80 percent in northwestern Russia down to single-digit percentages along the African Sahel during the same event.

UAE Visibility Window and Magnitude

From Dubai the eclipse began near 14:42 local time, peaked close to 15:53 and ended at 16:58, with an obscuration of approximately 40 percent. Abu Dhabi and Al Ain saw comparable timings. Residents who checked time.now/dubai, time.now/abu-dhabi or time.now/al-ain could line up arrival at desert venues such as Mushrif Park before first contact and stay until the Moon left the solar limb.

The Sun was already descending toward the western horizon during maximum eclipse, which created beautiful photographic compositions with palm trees and distant Dubai skyline. Observers with east-facing balconies needed to relocate; west-facing locations and any open desert site offered uninterrupted views from first to last contact, the entire event lasting just under two hours and twenty minutes.

Eye Safety: This Is Non-Negotiable

Looking at any part of the Sun without protection can cause permanent retinal damage. Use only eclipse glasses or solar filters that comply with the ISO 12312-2 standard. Sunglasses, smoked glass, exposed film and water reflections are not safe. Never point a telescope, binoculars or camera at the Sun without a full-aperture solar filter fitted in front of the objective lens.

Damage from solar viewing is painless because the retina has no pain receptors, which makes carelessness especially dangerous. Symptoms of solar retinopathy may not appear for hours and can be permanent. Inspect every pair of eclipse glasses before use, discarding any with scratches or pinholes. Supervise children continuously and remove glasses only when looking away from the Sun.

Telescope vs Naked-Eye Viewing

The naked-eye view through ISO 12312-2 glasses shows the crescent Sun cleanly and is ideal for children. A small refractor with a white-light solar filter reveals sunspots crossing the photosphere and crisp lunar limb detail. A hydrogen-alpha telescope adds prominences and chromospheric structure, dramatically enhancing the experience for visitors at our Mushrif Park sessions.

Pinhole projection offers a third route: punch a small hole in cardboard and let the Sun's image fall on a sheet of white paper below. Multiple pinholes produce multiple crescent images. A kitchen colander projects dozens of crescents simultaneously, a memorable demonstration we offer for school groups and a safe, no-equipment activity for families exploring eclipses for the first time.

Solar Photography Technique

To photograph the eclipse, fit a certified solar filter on the front of the lens and meter normally. A 400 to 800 mm focal length yields a generous solar disk on a crop sensor. Use a sturdy tripod, low ISO, and bracket exposures around 1/500 s at f/8. Capture sequences at five-minute intervals to compose a multi-phase mosaic after the event.

For smartphone images, hold the phone steady against an eyepiece fitted with a filtered telescope; afocal capture produces surprisingly clean results. Live View on a DSLR avoids any need to look through the optical viewfinder while the Sun is in the frame. Always remove the filter only after fully detaching the camera from the Sun and pointing the lens elsewhere.

Educational and Cultural Significance in the UAE

The 2022 partial eclipse aligned with the UAE's continuing investment in space science, including the Hope Probe and the Mohammed bin Rashid Space Centre. Al Thuraya Astronomy Center used the occasion to host school groups, distribute eclipse glasses and explain the Saros cycle that governs eclipse recurrence. See also NASA Sun for solar background.

Eclipses have a long history in Arabian astronomy: medieval astronomers from Baghdad, Cairo and Andalusia recorded eclipse timings to refine lunar and solar theories that fed into later European tables. Modern UAE eclipse outreach builds on that scientific heritage by combining safe observation, accessible explanations and contemporary instruments, ensuring every generation has a stake in the next great solar event.

Frequently Asked Questions

Was the 2022 partial solar eclipse visible from all UAE emirates?

Yes. The eclipse was visible across Dubai, Abu Dhabi, Sharjah, Ajman, Ras Al Khaimah, Fujairah, Umm Al Quwain and Al Ain. Maximum obscuration varied only slightly between emirates, so any open site with a clear western horizon offered a good view.

How much of the Sun was covered from Dubai?

At maximum eclipse from Dubai the Moon covered approximately 40 percent of the Sun's diameter. The crescent shape was easy to see through certified eclipse glasses and very striking when projected through a pinhole onto a sheet of white paper.

Are sunglasses safe for viewing a partial solar eclipse?

No. Ordinary sunglasses, even very dark ones, transmit far too much infrared and visible light to be safe. Always use ISO 12312-2 certified eclipse glasses or a properly mounted full-aperture solar filter on telescopes, binoculars and cameras.

When is the next significant solar eclipse visible from the UAE?

Solar eclipses recur every few years on average across any given region. Check the NASA Eclipse Web Site for upcoming events. The UAE will continue to enjoy partial phases of eclipses whose paths of greater coverage cross neighbouring regions.

Did Al Thuraya host a public viewing for the 2022 eclipse?

Yes. We operated filtered telescopes at Mushrif Park, distributed ISO-certified eclipse glasses and ran short talks on the Sun and Moon. Families were able to project the eclipse using simple pinhole cards as well.
