transits

Data-Driven Astrology 💫 Kerykeion is a Python library for astrology. It generates SVG charts and extracts detailed structured data for birth charts, synastry, transits, composite charts, and more.

A modern Python library for astrological chart calculation, visualization, reporting and data analysis. Built on the Swiss Ephemeris for astronomical accuracy.

Efficient detection of planets transiting quiet or active stars

No-BS astrological calculations validated against NASA, JPL Horizons & Swiss Ephemeris. Birth charts, transits, progressions that actually work.

Create and manipulate stellar light curves!

A package for detecting, vetting, and modelling transiting exoplanets on uncertain periods

SOAP is an open-source Python package that simulates the impact of stellar activity and planetary transits on spectroscopic, radial velocity, and photometric data.

Full-spectrum astrological computation engine. Swiss Ephemeris on bare metal. 16 CLI modes: natal, transit, synastry, composite, solar return, progressions, lunar, planetary hours, Arabic Lots, Hellenistic, dignities, antiscia, prediction, geoastrology, aspect grids. Norse/Rune overlays.

Visual Vetting and Analysis of Transits of Space ObservatioNs

Astrology UI components for the web: natal chart wheels, Vedic kundli, Human Design bodygraphs, tarot spreads and more. Drop in, themed, live in minutes.

The Public Photometry Pipeline for Exoplanets

Prediction of Exoplanet Precisions using Information in Transit Analysis

The (Exoplanet Detection Identifier) EDI-Vetter is the rock'n roll love child of Terra and RoboVetter, optimized to vet K2 transit signals.

Observation metrics for periodic events

AstroGods provides in-depth birth chart interpretations, synastry analysis for relationships, daily and monthly transit readings

Official HumanDesign.ai MCP for charts, bodygraph images, authorized libraries, reports, transits, and platform workflows.

An astrological calculation REST API. Provides endpoints for natal charts, planetary positions, retrograde calendars, transits, progressions, synastry, composite charts, solar returns, and daily/weekly/yearly forecasting.
