What's Changed

🔭 This release introduces the getQIndex() function, which in turn calculates a Q index for your observation for a particular moment in time.

There also includes a fix which accounts for the boundary condition in convertEquatorialToHorizontal when calculating the arcsine value, which has boundaries between [-1,1].

This release also includes the first batch of Constellations, however, the full set will follow in future versions.

v0.46.0

What's Changed

🔭 This module adds a useful q() utility parameter, which is a normalised quality index of an observation, taking into account the Moon's illumination, the angular separation between the target object and the Moon, the Sun's altitude (taking into account astronomical twilight starting at -18 degrees below the local horizon) and the target's altitude (assuming a horizon of +6 degrees for enhanced observations).

In subsequent releases, we will be exposing a function that can calculate the q based of off an observer's location, a target object and a particular datetime of observation.

Features

  • feat: add q() utility to calculate the quality index in @observerly/astrometry by @michealroberts in #263
  • feat: add getAntipodeCoordinate() to astrometry module in @observerly/astrometry by @michealroberts in #261

Refactors

  • refactor: amend getLunarAngularDiameter() utility in moon module in @observerly/astrometry by @michealroberts in #257

Fixes

  • fix: amend lunar Δ (in AU) calculation getLunarAngularDiameter() in moon module in @observerly/astrometry by @michealroberts in #258

Validity & Testing

  • test: add suite for antipodal tests for getAngularSeparation() in @observerly/astrometry by @michealroberts in #259

What's Changed

🔭 This release introduces the possible to calculate if for a given location on Earth, at a specific time, there will either be a Solar or Lunar eclipse.

The API is exposed as isSolarEclipse() and isLunarEclipse(), (both take in the same parameter arguments) e.g.,:

import { isSolarEclipse } from '@observerly/astrometry'

// Give me an observer that is based in Truro, Cornwall, UK
const observer = {
  latitude: 50.2632,
  longitude: -5.051,
  elevation: 0
}

const datetime = new Date('1999-08-11T11:04:00Z')
const eclipse = isSolarEclipse(datetime, observer)

console.log('11th August 1999', eclipse)
11th August 1999 {

v0.42.0

What's Changed

🔭 This minor release adds the findPlanetaryConjunctions() utility, to calculate when two planetary bodies are in conjunction with each other, e.g., Jupiter and Venus. This paves the way for solutions to be found for #229 and further conjunction analysis across a number of bright and visible-with-the-naked-eye objects.

This release also amends the ConjunctionParams type in a non backwards-compatible way.

This release also ensures that the new Moon phase is calculate to a higher degree of accuracy.

Features

  • feat: add getPlanetaryPositions() utility helper to planets module in @observerly/astrometry by @michealroberts in #225
  • feat: add findPlanetaryConjunctions() to conjunction module in @observerly/astrometry by @michealroberts in #228
  • feat: add getNextNewMoon() to moon module in @observerly/astrometry by @michealroberts in #234

Refactors

  • refactor: amend getLunarPhase() { age } lookup for WaningCrescent in @observerly/astrometry by @michealroberts in #233
  • refactor!: amend usage for "ConjunctionParams" in conjunction module in @observerly/astrometry by @michealroberts in #224
