Western Daily Transits
asterwise_get_western_transits_daily
Current sky positions vs natal chart for a single day. Returns all 10 planets with tropical longitudes and active aspects to natal positions using transit orbs: major 3°, sextile 2°, minor 1°. Provide start_date for a specific day; defaults to today.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
birth | object | yes | Birth data for Western astrology tools (tropical zodiac). Fields: date, time, lat, lon, person_name, timezone, house_system |
response_format | enum: markdown, json | no | Output format: 'markdown' (default) for a readable report, or 'json' for the raw structured payload. |
start_date | string/null | no | Start of the window, YYYY-MM-DD. Defaults to today when omitted. |
What it covers
Single-day transit snapshot: where each planet is now versus where each natal planet was at birth, with applying/separating transit-to-natal aspects using tighter transit orbs than natal chart orbs. Excludes progressions and solar arc — pure transit ephemeris.
Workflow
BEFORE: asterwise_get_western_natal — establish natal chart first.
AFTER: asterwise_get_western_transits_weekly — for week view.
Input
birth — WesternBirthData (date, time, lat, lon, timezone). house_system ignored for this endpoint.
start_date (optional YYYY-MM-DD) — defaults to today.
Output contract
data.date, data.transit_planets[] — name, longitude, sign, is_retrograde, aspects_to_natal[]
data.aspects[] — transit_planet, natal_planet, type, orb, is_applying
data.total_aspects
Response format
response_format=json serialises the complete response as indented JSON.
response_format=markdown renders the same data as a human-readable report.
Both modes return identical underlying data.
Compute class
MEDIUM_COMPUTE (~400ms)
Errors
INVALID_PARAMS (local): WesternBirthData validation failures.
INTERNAL_ERROR: Any upstream API failure or timeout → MCP INTERNAL_ERROR
Edge cases:
Transit orbs are smaller than natal orbs: major 3°, sextile 2°, minor 1°.
Do not confuse with
asterwise_get_western_transits_weekly — 7 days vs 1 day.
asterwise_get_western_transits_monthly — 30-day window vs single day.
