A partial eclipse of the Sun occurred on Thursday 23 October, 2014 UT, lasting from 19:37–23:51 UT. This was a deep partial eclipse, with 81% of the Sun covered for viewers closest to the center. This provided a significant spectacle for those who saw it over most of the USA (except the eastern side), western Canada, and Mexico.

The timings of the phases of the overall eclipse worldwide are as follows. In any particular place it would have been seen for a significantly shorter duration as the shadow moved across the Earth:

Partial eclipse began: 19:37:33 UT
Maximum eclipse: 21:44:32 UT
Partial eclipse ended: 23:51:40 UT

During this eclipse the Sun was 0.536° in apparent diameter, 0.5% larger than average. The Moon was 5 days after apogee and 10 days before perigee. At maximum eclipse it was 0.508° in apparent diameter, which is 4.3% smaller than average. This has no real effect on this eclipse, since the Moon's central shadow misses the Earth, making this a partial eclipse. The statistics page has information on the ranges of the sizes of the Sun and Moon, and the Moon data page displays detailed information on the Moon's key dates.

Sunspot Flash!

A gigantic sunspot cluster, AR 2192, was crossing the Sun's face during the eclipse. This was visible during the eclipse (and before and after it, for that matter), with proper safe observing techniques; even just looking through eclipse glasses, it was quite visible.

The eclipse just after maximum in Palo Alto, CA; photographed in a simple Sun projector. Note that the image is upside-down. Active Region 2192 is clearly visible. The observing page has information on making a projector like this.


The partial eclipse will be visible in the Russian Far Eastern Federal District and most of North America, excepting the north-east. In eastern regions the eclipse will be happening at sunset, so a clear view of the horizon is required, and the full eclipse may not be visible depending on where you are. As always, a clear sky is essential, so check the weather and head for where there's the least chance of clouds.

The partial eclipse wil begin over eastern Siberia and the Kamchatka Peninsula at sunrise. Most of Magadan Oblast, the eastern end of the Sakha Republic, and western Chukotka will see the sun rise after maximum eclipse; most of Chukotka and most of Kamchatka will see the sun rise before maximum, which will occur around 20:30 UT. Eastern Chukotka will see the entire eclipse, with the maximum around 20:50 UT.

Alaska, Canada

The greatest eclipse will be seen in extreme northern Canada, where the Sun wil be seen 80% covered. In Alaska except for the south-west, an eclipse of over 60% will be seen, with the maximum eclipse ocurring between 21:00 UT in the west and 21:30 UT in the south-east. Most of Canada will also see a 60% or greater eclipse, with the maximum around 22:00 UT across Alberta, and shortly later in Saskatchewan. In Manitoba and western Ontario, the Sun will set after maximum eclipse, so the whole eclipse will not be visible; in eastern Ontario and western Quebec, only the earlier stages of the eclipse will be visible before sunset, and farther west, it will not be seen at all.

Lower 48, North

In the lower US, a 60% or greater eclipse will be seen in Washington state, northern Oregon, Idaho north of the Snake river, Montana, northern Wyoming, the Dakotas, Minnesota, and northern Wisconsin. In Washington, maximum eclipse occurs at 22:00 UT; in South Dakota and northern Minnesota it comes at 22:30 UT. From the Dakotas east, the sun will be setting during the eclipse, and from Michigan east, it will set before maximum eclipse. The far north-eastern states will struggle to see any eclipse at all.

Lower 48, South

Farther south, a 40% eclipse or more will be visible in California and the south-western US states, including northern Texas, Oklahoma, Arkansas, northern Mississippi, and northern Alabama. San Francisco will see the Sun close to 50% obscured at around 22:15 UT; likewise most of Nevada, Utah, Colorado, and Kansas, as well as points north, can look forward to a 50% or greater eclipse.

From Kansas, Oklahoma and eastern Texas eastwards, the Sun will set during the eclipse; and from Florida, Georgia and Ohio eastwards, it will set before maximum eclipse. Louisville, KY, will see maximum eclipse almost exactly at sunset — for those with a clear view to the horizon.

Note that while all dates and times on this site (except where noted) are in UT, which is within a second of civil time, the dates and times shown in NASA's eclipse listingsGSFC Eclipse Web Site

are in the TDT timescale.

The Sun and Moon distances are shown in km, and as a percentage of their minimum - maximum distances; hence 0% is the closest possible (Earth's perihelion, or the Moon's closest possible perigee) and 100% is the farthest (aphelion, the farthest apogee). The statistics page has information on the ranges of sizes of the Sun and Moon, and the Moon data page displays detailed information on the Moon's key dates.
