Solar Eclipse visiblity, September, 2015:

Antarctica and South African Continent:

Eclipse type: Solar Partial:

 

Antarctica: maximum; approximately 70.96% obscurity.

 

The following countries will have a partial

solar eclipse to varying amounts of obscurity:

 

Partial Eclipse visible: South African continent

 

  • Angola (south)  Luiana National Park,  01.44%

        or (Coutada publica do Luiana)

  • Botswana, Gaborone,  .  .  .  .  .  .  .  .  .    12.93%

  • Lesotho,  Maseru.  .  .  .  .  .  .  .  .  .  .  .    20.92%

  • Malawi (south) Zomba .  .  .  .  .  .  .  .  .     00.02%

  • Mozambique (central and south) Maputo 13.97%

  • South Africa, Pretoria.  .  . .  .  .  .  .  .  . .   14.52%

  • Swaziland, Mbabane .  .  .  .  .  .  .  .  .  .    14.92%  

  • Zambia (central and south)  Harare.  .  .    02.32%

 

  • Zimbabwe, Windhoek, Eclipse at sunrise: 09.72%

 

Madagascar

Madagascar, (central to south),Antananarivo      01.27%

 

 

South Africa towns and cities: obscurity:

  • George; .  .  .  .  30.12%

  • Johannesburg; 15.28%

  • Mossel Bay .  .   30:54%

  • Port Elizabeth    29.61%

  • Pretoria   .  .  .   14.52%S

  • Still Bay .  .  . .   30.95%

  • Cape Town 30.41%. 

  •  

  • Cape Town; (west South Africa) as can be seen with reference to the ‘Contact Region Map’ the eclipse is in process as the Sun is rising, so the entire eclipse is not possible to view.

Partial Eclipse in process as the Sun rises from: west South Africa; west to central Namibia; and south-west Angola.

 

Observers from the far southern countries of Africa are not well placed for viewing the partial solar eclipse.

 

Observers from southern South Africa have the best viewing opportunities. Obscurity from Port Elizabeth is: 29.61% obscurity: George has, 30.12% obscurity; Mossel Bay  30:54% obscurity, and Still Bay 30.95% obscurity.

Cape Town, in west South Africa; as can be seen with reference to the ‘Contact Region Map’ the eclipse is in process as the Sun is rising, so the entire eclipse is not possible to view.

Obscurity Cape Town 30.41%.

Travelling north lessens obscurity of the Sun. Johannesburg, 15.28%, and Pretoria 14.52% obscurity.

 

Antarctica has the Greatest Obscurity, approximately 70.96%.

 

The only major inhabited landfall from which the eclipse can be observed is southern Africa and Madagascar.

 

South Africa is the best placed country from which to view the eclipse (except the far west.)

 

South Africa is the best placed country from which to view the partial solar eclipse, and the further south you are, the better you can see it. However, in west South Africa the eclipse is occurring as the Sun is rising and so the entire eclipse is not visible.

 

 

 

Travelling north lessens obscurity of the Sun.

Orange region 1: Sunrise: Maximum eclipse occurs before the Sun has risen.

Yellow region 1:  Sunrise: Sun rises during maximum eclipse.

 

White region: Partial eclipse visible.

 

Yellow region 2:   Sunset: Sun sets during maximum eclipse.

Orange region 2: Sunset: Maximum eclipse occurs with the Sun below the horizon. 

 

 

Maximum obscurity: Antarctica: 70.96%.

Minimum obscurity: mid Angola; mid Zambia; south Malawi; north Mozambique;

north Madasgascar. 00.01%

 

Solar Eclipse September 2015 is a Southern Hemisphere celestial event:

2015 September Greatest Eclipse; Antarctica; approximately 70.96% obscurity:

 

The partial solar eclipse of September 2015 is a Southern Hemisphere celestial event, with maximum obscurity over a remote area of Antarctica. Obscurity at its Greatest from Antarctica is approximately 70.96%, but it is likely that few, if anyone will be able to view the eclipse at its Greatest.

 

The only major landfall from where the eclipse can be observed is southern Africa and central to southern Madagascar. From here, the eclipse sweeps over vast areas of the remote Indian Ocean.  

 

September 2015 Solar Eclipse belongs to

Saros Series 125

 

The 2015 September solar eclipse occurs at the Moon's ascending node. It belongs to Saros Series 125 and is member number 54 of 73.

 

Saros Series 125 began on Saturday, 04 February 1060 as a partial solar eclipse over the Arctic, near the North Pole.

 

Since then, every subsequent eclipse has moved southwards, and the series will end as a partial solar eclipse over Antarctica, near the South Pole on Wednesday, 09 April 2358.

 

Saros Series 125 has a duration of 1,298.17 years. All its remaining eclipses are partial.

The September Solar Eclipse 2015 is the second solar eclipse of the year.

 

The solar eclipse of September 2015 is the second solar eclipse of 2015, and the third eclipse of the year. It follows the Total Solar Eclipse, 20 March, and the Total Lunar Eclipse of 04 April 2015.
