This solar eclipse is the SEVENTH ANNULAR ECLIPSE OF THE SUN of the XXIth century.

It will be visible in partial form on three continents:
– south of AFRICA – SOUTH and SOUTHEAST of ASIA and in OCEANIA.

Its central band will be visible in ANNULAR ECLIPSE form only on the Territory of COCOS (Keeling) islands, in INDONESIA (on the island of Sumatra, the island of Borneo and on the north of the island of Celebes) and in MALAYSIA (on the island of Borneo at the extreme south of the State of Sarawak).

This ANNULAR ECLIPSE will be visible in partial form in SOUTHERN AFRICA, in MADAGASCAR, on the REUNION island, on MAURITIUS, in SOUTH ASIA, in SOUTHEAST ASIA and in OCEANIA.


The Annular eclipses, because of their rarity and the show which they give us, are all the more fascinating to observe.
But it is therefore all the more important to protect one's EYES, during all the various phases of an annular eclipse. (See chapter PROTECT YOUR EYES)

We have a SOLAR ECLIPSE when the EARTH passes in the cone of umbra or the cone of penumbra of the MOON. The SUN, the MOON and the EARTH are then practically aligned and this when the new MOON approaches. Therefore SOLAR ECLIPSES occur on the new MOON.

The disc of the MOON being an insufficient diameter to hide the SUN entirely (conversely to a total eclipse), there remains a slim ring of the SUN around the black disc of the MOON.
Indeed, according to the distance of the MOON in comparison with us, this ring will be more or less fine.
In this case there is an ANNULAR ECLIPSE OF THE SUN.

It remains however an unusual show across our safety glasses "SPECIAL ECLIPSE" you will see a big black disc at the time of the ANNULAR PHASE - the MOON - passing in front of the SUN.

The conical umbra is accompanied by a penumbra zone where a part of the SUN remains visible. The ECLIPSE is PARTIAL in this zone.
If the EARTH passes only in the cone of penumbra of the MOON we have a PARTIAL ECLIPSE OF THE SUN.


THE PHENOMENON

On the other side of the MOON in relation to the SUN, two zones can be distinguished:
• An UMBRA ZONE in which it is almost completely dark, because a big party of the surface of the SUN is hidden: the ECLIPSE is ANNULAR.
  This zone is in the form of a tapering cone and it is the tip of this cone that will sweep across land.

• A PENUMBRA ZONE where part of the SUN remains visible and where the ECLIPSE is only PARTIAL.
  The rest of the country will be in this area.

The CORONA, this luminous outer atmosphere around the MOON, can only be observed when the entire lunar disc partially covers the SUN.
This is why ANNULAR ECLIPSES OF THE SUN are rare and much sought-after phenomena.

Just before the ANNULAR ECLIPSE, the luminous atmospheric ring around the SUN breaks into spots of light. This effect is caused by the final specks of sunlight shining through gaps between the lunar mountains.
Almost all the luminosity of the photosphere has disappeared and the corona shines like a pearly white ring, sometimes in an irregular shape, around the SUN.


The ANNULAR ECLIPSE has now begun. The entire horizon may take on an orange or claret colour, similar to the colour of the sky after a sunset.
Stars and bright planets may be visible during an ANNULAR ECLIPSE.
The sun's corona may now be clearly visible. When the SUN is at the height of its activity the corona can appear as a broad ring.

The sky darkens considerably and plants and animals react to the increase in darkness. Some flowers may close. Animals may behave as they do when night falls.
As the light fades more rapidly, the surroundings may start to look metallic-grey and shadows become better defined.
The temperature can also fall by several degrees.
