The annular ring is quite thick because the Moon appears only 95% the diameter of the Sun. The duration of the annular phase reaches the 6-minute mark here at 00:15 UT. This is the last major landfall in the path.Īs the antumbral track curves to the east, it encounters Tarawa atoll in the Gilbert Islands (Republic of Kiribati). Traveling at 0.98 km/s, the antumbra next reaches the Solomons where Choiseul, the largest island in the chain, lies at the center of the track.Īnnularity is now 5 minutes 16 seconds and the Sun is 49° above the horizon (23:15 UT). The central line crosses Basilaki Island where annularity lasts 4 minutes 59 seconds with the Sun at an altitude of 39°. The next landfall in the eclipse path occurs in eastern Papua New Guinea at 23:00 UT. The antumbral shadow crosses the Gulf of Carpentaria and reaches the Cape York Peninsula at 22:44 UT.Īs it does so, it crosses the track of the previous year's total solar eclipse (2012 November 13).įour minutes later, the shadow departs Australia at Lakefield National Park (22:48 UT). On the central line 70 km to the north, annularity lasts 4 minutes 27 seconds at 22:37 UT.
Since the eclipse occurs here shortly after sunrise, the Sun is just 16° above the horizon. Traveling northeast, the shadow quickly sweeps across the Northern Territory where Tennent Creek experiences an annular phase of 3 minutes 4 seconds. The annular path begins in Western Australia near Collier Range National Park at 22:33 UT.īecause the Moon passes through apogee just 3 1/2 days later (May 13 at 13:32 UT), its large distance from Earth produces a wide path of annularity. The first solar eclipse of 2013 occurs at the Moon's descending node in eastern Ares.Īn annular eclipse will be visible from a 171 to 225 kilometre-wide track that traverses Australia, eastern Papua New Guinea, the Solomon Islands, and the Gilbert Islands.Ī partial eclipse is seen within the much broader path of the Moon's penumbral shadow, which includes Australia, Indonesia, Oceania and much of the central the Pacific Ocean ( Figure 2).
#SOLAR ECLIPSE MAESTRO SERIES#
In particular, the April 25 event is the last partial eclipse in Saros 112.Ĭomplete details for the series can be found at:Į/LEsaros/LEsaros112.html The April 25 eclipse belongs to Saros 112, a series of 72 eclipses in the following sequence: 7 penumbral, 21 partial, 15 total, 22 partial, and 7 penumbral lunar eclipses (Espenak and Meeus, 2009). To catch the entire event, one must be located in eastern Europe or Africa, central Asia or western Australia.Īt the instant of greatest eclipse the Moon will be at the zenith for an observer just east of Madagascar.Įastern parts of South America will experience moonrise with the eclipse already in progress, but none of the eclipse is visible from North America. This event is barely partial with just 0.5 arc-minutes of the Moon's northern limb dipping into umbral shadow.Ĭonsequently, the partial phase lasts less than 27 minutes.įigure 1 shows the path of the Moon through the penumbra and umbra as well as a map of Earth showing the regions of eclipse visibility.
The Moon's contact times with Earth's shadows are listed below.Īt the instant of greatest eclipse the umbral eclipse magnitude will reach 0.0147. It is visible primarily from the Eastern Hemisphere. The first lunar eclipse of 2013 occurs at the Moon's ascending node in southern Virgo about 12° east of Spica (mv = +1.05). The lunar eclipse diagrams also include the path of the Moon through Earth's shadows.Ĭontact times for each principal phase are tabulated along with the magnitudes and geocentric coordinates of the Sun and Moon at greatest eclipse. World maps show the regions of visibility for each eclipse. Predictions for the eclipses are summarized in Figures In 2013, there are two solar eclipses and three lunar eclipses as follows.
