Timezone / Date

You have not selected a timezone for eclipse timings, so all times are shown in UT (essentially GMT).

Accuracy

Due to the erratic rotation of the Earth, the time and location of the eclipse cannot be forecast perfectly. This eclipse's forecast is estimated to be accurate to within 2km in distance and a few seconds in time.

A partial eclipse of the Sun occurred on Saturday 11 August, 2018 UT, lasting from 08:02–11:30 UT. A moderate partial eclipse, with 74% of the Sun covered for viewers closest to the center, created an interesting spectacle for observers from the Arctic, Greenland, Scandinavia, and north and east Asia.

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: 08:02:05 UT
Maximum eclipse: 09:46:15 UT
Partial eclipse ended: 11:30:39 UT

During this eclipse the Sun was 0.526° in apparent diameter, 1.3% smaller than average. The Moon was at perigee, making it fairly large. At maximum eclipse it was 0.555° in apparent diameter, which is 4.6% larger 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.

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

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.
