The second of two 2022 partial solar eclipses occurs Tuesday, Oct. 25, as a Northern Hemisphere event that favors northeastern Africa, western Asia and most of Europe.

The year's first partial solar eclipse opened the 2022 eclipse lineup Saturday, April 30, as the first of the year's quartet of two partial solar and two total lunar eclipses. The year's first partial solar eclipse's exclusive favoring of the Southern Hemisphere contrasts with the year's second partial solar eclipse's Northern Hemisphere exclusivity.

Continentally, the October partial solar eclipse favors large parts of the three continents of Africa, Asia and Europe. A slice of southeastern Greenland qualifies North America for inclusion in the partial solar eclipse's geographic regions of visibility. Oceanically, the October partial solar eclipse favors the far northeastern Atlantic and portions of the Arctic and northern Indian oceans.

First contact between Earth's surface and the lunar penumbra (P1) signals the start of October's partial solar eclipse. First contact takes place Tuesday, Oct. 25, at 08:58:10.3 Universal Time (4:58 a.m. Eastern Daylight Time), according to NASA astrophysicist, now emeritus, Fred Espenak's eclipse predictions on the NASA Eclipse Web Site.

Greatest eclipse (GE) indicates the instant of closest passage of the lunar shadow cone's axis to Earth's center. The October partial solar eclipse achieves greatest eclipse at 11:00:00.4 UT (7:00 a.m. EDT).

Greatest eclipse will occur over northwestern Russia's northern Ural Federal District in northwestern Asia. The area qualifies as the October partial solar eclipse's greatest eclipse location but the event's ending after the sun's local sunset time of 4:25 p.m. Yekaterinburg Time (YEKT) prevents all-eclipse visibility.

Last contact between Earth and the lunar penumbra (P4) announces the October partial solar eclipse's closure. October's partial solar eclipse terminates at 13:02:07.7 UT (9:02 a.m. EDT; 6:02 p.m. YEKT).

Southeastern Greenland misses the beginning of October's partial solar eclipse because of the sun's location below the horizon. Ittoqqortoormiit in southern Greenland's Sermersooq municipality clocks sunrise at 9:29 a.m. Eastern Greenland Summer Time (EGST), half an hour after the eclipse's local below-horizon start time of 8:59:02 a.m. EGST, according to the Time and Date website. Time and Date recommends unobstructed observation sites with clear views to the southeast because of the sun's closeness to the horizon through October's partial solar eclipse. Ittoqqortoormiit witnesses the instant of greatest eclipse at 9:51:48 a.m. EGST. October's partial solar eclipse ends at 10:45:59 a.m. EGST.

Sunset's occurrence prior to the October partial solar eclipse's ending is responsible for the October partial solar eclipse's incomplete visibility in Surgut, the largest settlement in Ural Federal District's Khanty-Mansi Autonomous Okrug–Yugra in northwestern Russia. Also, the sun's closeness to the horizon requires observation from unobstructed sites with clear views to the west-southwest. Surgut's start of October's partial solar eclipse happens at 2:50:39 p.m. Yekaterinburg Time (YEKT). Greatest eclipse occurs at 3:59:22 p.m. YEKT. The sun sets at 4:25:26 p.m. YEKT, 39 minutes before the eclipse's below-horizon ending at 5:04:28 p.m. YEKT.

The Iberian Peninsula falls within and without the geographic regions of visibility for October's partial solar eclipse. Portgual is excluded for eclipse visibility. Northwestern, central and southern Spain miss the event.

October's partial solar eclipse begins at 11:32:59 a.m. Central European Summer Time (CEST) for Barcelona, capital of the autonomous community of Catalonia (Catalan: Catalunya) in northeastern Spain. Greatest eclipse takes place at 12:07:36 p.m. CEST. The event ends at 12:43:04 p.m. CEST.

Northeastern Africa's Egypt falls within the geographic region of all-eclipse visibility for October's partial solar eclipse. Northeastern Egypt's port city of Alexandria welcomes the event's start at 11:56:01 a.m. Eastern European Time (EET). Greatest eclipse takes place at 1:05:16 p.m. EET. The eclipse ends for Alexandria at 2:12:21 p.m. EET.

As viewed from Earth, the placement of the moon between Earth and the sun produces a solar eclipse. A partial solar eclipse arises from the moon's incomplete coverage of the sun.

The takeaways for the Tuesday, Oct. 25, occurrence of the second of two 2022 partial solar eclipses are that October's partial solar eclipse exclusively favors the Northern Hemisphere in contrast with the Southern Hemisphere exclusivity of the year's first partial solar eclipse, Saturday, April 30; that October's partial solar eclipse offers varying degrees of visibility to the four continents of Africa, Asia, Europe and North America; and that parts of three oceans (Arctic, Atlantic, Indian) experience varying degrees of visibility of October's partial solar eclipse.
