A Node module for generating planetary ephemeris data for a given date and location. This module repurposes code originally published by Ole Nielsen in 2002 and Peter Hayes in 1999.
Blastro will generate ephemeris data for planetary bodies for any given date and location. This data can be used for astronomical and astrological interests.
This is a barebones implementation of one of Ole Nielsen's ephemeris functions. I plan to continue to develop this module and aim to create the standard for javascript ephemerides. If you would like to contribute, please issue a pull request.
To install this module, simply run:
npm install blastro
Currently, this module exports a single function (returnAllPlanets). The single argument to this function is an object in the following format:
obs = {
day: 14, //integer
dst: false, //daylight savings time, boolean
hours: 6, //integer
latitude: "42:43:38", //string in this format
longitude: "82:43:00", //string in this format
minutes: 50, //integer
month: 11, //integer
name: "Location", //string
seconds: 0, //integer
tz: 0, //timezone correction from GMT
year: 2014 //integer
};
