The week 15th – 21st September 2025

The Geo-Zenith forecast for the week of 15–21 September 2025: the week sits inside a tight eclipse season whose mechanical centre is the partial solar eclipse on 21 September. Astronomically that new-moon/eclipse takes place across the South Pacific and registers as a deep partial (greatest eclipse ≈ 19:43–19:55 UTC), so while it will not be widely visible across Europe it nevertheless marks a global nodal reset in the ecliptic that tightens polarities and accelerates endings and new starts. Practically, treat the 21st as a deadline energy: projects, narratives and reputations that have been simmering will either be closed down or forced into a new, visible form around that date.

Above and beneath that focal eclipse you have a distinctly Virgoan foreground: the Sun and Mercury remain in Virgo for this week, emphasising classification, repair and rhetoric that must be serviceable rather than pretty. That placement privileges tidy records, inventories and the practical re-coding of what is useful; Mercury in Virgo will be busy reducing myth to checklist, which makes it an excellent week for editing, publishing clear timelines or compiling evidence rather than chasing grand narratives. Use the Virgoan window to file what the eclipse will later reconfigure; the ephemerides show the Sun and Mercury firmly engaged in Earth-sign work through this interval.

There is an undercurrent of Uranian shock and ancestral imagery leftover from the recent Moon–Pleiades appulse (12 September) and Uranus lingering in the Taurus sector nearby. The literal sky event — the Moon’s close approach to the Pleiades with Uranus in the same patch of Taurus — seeded the collective with sudden recollections or data-drops about lineage, networks and what counts as “home.” In Geo-Zenith terms that combination reads as old loyalties being contacted by an outside intelligence: expect unexpected disclosures about origins, sudden returns of archival material, or technical leaks that reshape how a family or institution tells its story.

How to work with this week: log and date everything you or others publish between the 15th and the 21st and treat the 21st as a cut-off for structural decisions. Keep language precise and auditable — Mercury in Virgo rewards plain records; avoid speculative grandiosity. If something abrupt lands (Uranus-style) don’t treat it as the whole story; file it, cross-check against older records and let the eclipse purge what’s built on poor documentation. For deeper context, the richer, longer-form takes from experienced technical astrologers (the Astrology Podcast and Bernadette Brady’s eclipse analyses) are the kind of sources worth consulting when you want methodical, layered readings rather than headline horoscopes.

To move through this week well: keep a journal; mark the moments of deep insight or discomfort, especially around the middle (17-19) and on the 21st. Before acting, wait for clarity—let the eclipse close the chapter cleanly. Ground yourself through daily rituals, practical service, and honest inner listening. In that space you’ll cross the threshold not just changed, but more truly aligned.

3I Atlas trajectory

The solar system is being traversed by an interstellar visitor of extraordinary proportions, known as 3I/ATLAS. Unlike the brief flyby of its predecessors, this object moves along a trajectory almost parallel to the ecliptic plane, threading through the inner planets at a retrograde inclination of 175 degrees. Its current velocity is around 58 kilometres per second, accelerating to roughly 68 kilometres per second as it nears perihelion on 29 October 2025. The object is enormous: estimates place its nucleus at 46 to 50 kilometres across, while its coma, rich in carbon dioxide and plasma, already spans nearly 700,000 kilometres which is half the diameter of the Sun! This dusty, electrically charged envelope renders this visitor highly active as it interacts with the solar wind and heliospheric currents, particularly during the heightened activity of our current solar maximum.

This trajectory will take it just above Mars in early October, past the asteroid belt, and later toward Jupiter by March 2026. Along the way, it will traverse the electromagnetic environment of the inner planets and their moons, and subtly influence dwarf planets such as Ceres, Haumea, Makemake, and Eris. Its plasma tail and ionised gases will interact with solar, ultraviolet and X-ray radiation, expanding and energising the coma, while the gravitational and magnetic fields of the planets will shape its outbound trajectory. Though no physical contact is expected with any planetary body, its presence represents a rare moment of systemic resonance, as interstellar material and electromagnetic energy thread through the solar system over the next few months.

From an astrological perspective, the geo-zenith alignments of this period intensify the already volatile planetary currents. September begins with two eclipses – the solar on the 7th and the lunar on the 18th—priming collective awareness and initiating subtle systemic shifts. We will already be aware that change is in the air. The object’s close passage to Mars coincides with a new moon and a superior conjunction with Earth, amplifying perception and reflection on structural and emotional frameworks. Its perihelion near the Sun acts as an energetic fulcrum, enhancing interactions across the Virgo-Pisces axis, while its outbound movement past Jupiter in March resonates with expansion, insight, and recalibration of broader societal and philosophical patterns. Dwarf planets and inner moons act as secondary nodes in this network, subtly modulating the energetic and astro-magnetic interplay. The world will be so changed – as will we.

3I/ATLAS is not just a celestial visitor but a long-time catalyst, threading the solar system with interstellar energy and interacting with both planetary fields and collective consciousness. Its trajectory and electromagnetic presence provide a unique opportunity to observe the intersection of cosmic physics and geo-zenith astrology, a rare alignment of astronomical and systemic resonance that will unfold over the coming months, leaving subtle yet tangible imprints on both our solar environment and our planetary awareness. We may even get more images and readings from our satellites and telescopes – so keep watching.
