v0.45.0

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)
