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 time is estimated to be accurate ± 3m02s (with 95% confidence). This equates to an error in longitude of ± 0.76 degrees, or around ± 40 km (25 miles) at the latitude of greatest eclipse.

A partial eclipse of the Sun occurs on Thursday 4 May, 2152 UT, with maximum eclipse at 18:08 UT. A moderate partial eclipse, with 50% of the Sun covered for viewers closest to the center, will create an interesting spectacle.

Maximum eclipse is at 18:08:29 UT.

During this eclipse the Sun will be 0.529° in apparent diameter, 0.8% smaller than average. The Moon will be 5 days after apogee and 10 days before perigee. At maximum eclipse it will be 0.507° in apparent diameter, which is 4.5% 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.

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, and the Moon data page displays detailed information on the Moon's key dates.
