A partial eclipse of the Sun occurred on Thursday 9 July, 1964 UT, with maximum eclipse at 11:17 UT. A small partial eclipse barely darkened the Sun. With just 32% of the Sun covered for viewers closest to the center, this was of limited interest.

Maximum eclipse was at 11:17:18 UT.

During this eclipse the Sun was 0.524° in apparent diameter, 1.6% smaller than average. The Moon was just a day past perigee, making it fairly large. At maximum eclipse it was 0.553° in apparent diameter, which is 4.2% 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 listings 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.
