An annular solar eclipse will occur on September 1, 2016, which will be visible from Africa and some parts of the Atlantic and Indian Oceans. (Of course, for most viewers in Africa, it will be a partial one.) The eclipse will begin at 06:13 UTC; the maximum point will take place at 09:01 UTC, and the annularity will last for 3 minutes and 6 seconds.
When do annular solar eclipses happen? Just a short explanation.
As the Moon’s path around the Earth is elliptical, one side of the orbit is closer to Earth than the other. The point closest to the Earth is called the ’perigee’ and the point farthest from the Earth is known as the ’apogee’. When the Moon is farthest from the Earth, its apparent size is smaller than the Sun’s apparent size. Because of this, annular eclipses of the Sun can only occur when the Moon is near apogee – it is the only time when the entire disc of the Moon can block the central part the Sun’s disc, while leaving the outer parts of the Sun – an ’annulus’ (i.e. ’ring’) – visible. The ’antumbra’ is the region from which the occluding body appears entirely contained within the disc of the light source; an observer in this region experiences an annular eclipse, in which a bright ring is visible around the eclipsing body. Of course, like total solar eclipses, annular solar eclipses can be seen as partial eclipses from locations inside its ’penumbra’, but outside it’s ’antumbra’.
Many ancient civilisations have used ’eclipse cycles’ to predict eclipses and calculate their features. One of the most popularly studied eclipse cycles is the ’Saros cycle’; it is a period of approximately 6,585.3 days or around 18 years, 11 days and 8 hours and occurs due to a combination of 3 lunar cycles: the ’synodic’, the ’anomalistic’ and the ’draconic’ months. Any two eclipses separated by the same ’Saros cycle’ share very similar geometries. They occur at the same node with the Moon at nearly the same distance from Earth and at the same time of year. Because the ’Saros period’ is not equal to a whole number of days, its biggest drawback is that subsequent eclipses are visible from different parts of the globe. The extra 1/3 day displacement means that Earth must rotate an additional ~ 8 hours or ~ 120° with each cycle. For solar eclipses, this results in the shifting of each successive eclipse path by ~ 120° westward. Thus, a ’Saros series’ returns to about the same geographic region every 3rd occurrences (54 years and 34 days).
This eclipse – in the 10th degree of the tropical Virgo, in the middle of the sidereal Leo and, at the same time, in the Purva Phalguni Nakshatra – may be another indication of the violent astrological ’condensation’ about which I wrote in my recent post concerning the exact (Mars conjunct Saturn) conjunct Antares; as it makes an exact square to the Antares–Aldebaran axis (view the chartwheel).
During the next weeks, this eclipse can indicate some disharmonic life events for those having important planets on the 10th degree of the tropical Virgo / Pisces / Sagittarius or Gemini. In the context of the mundane astrology the countries and places connecting to the ’Virgo’ principle can be ’responsive’ like Brazil, Congo, Croatia, Greece, Switzerland, Turkey, Uruguay, Virgina (US); Baghdad, Basel, Boston, Padua, Paris, Los Angeles etc. (By experiences, nowadays, the ’effects’ of an eclipse aren’t simply localized to the path of the visibility, but, as a ’latent point’, it has ’influences’ on the correspondent principles all over the world.)
Finally some historical notes. The last solar eclipse in the 10th degree of the (’moving’) tropical Virgo was on September 1, 1682 (Saros 149, and it was a partial one); within this same Saros cycle (Saros 135) the last occurrence making an exact square to the Antares–Aldebaran axis, within an orb of 1.5 arcdegrees, happened on August 18, 1403 (it was a partial eclipse).
