Tropical Provided charts to Sidereal

Caveats

Synastry charts

Don’t mix sidereal with tropical charts for Synastry – it won’t work.

Don’t change the details of associated charts with a Synastry chart. The synastry chart may not work correctly. Better to cast the Synastry chart again.

AC ver 2.78

The AC sidereal module has had to be reviewed and some code amended. The introduction of adding aspects to house cusps caused some sidereal chart planetary layout problems.

Zodiac settings. Geocentric only. Sidereal or Tropical.

Please note that the Tropical zodiac is the default setting when first installing AC on your iPad. If you have no intention of using the sidereal option there is no need to do anything. Please continue as usual.

All chart screenshots use the Fagan/Bradley ayanamsha.

This is a chart setting so that if a chart is created or edited (and saved) the zodiac will either be Tropical or Sidereal depending on the setting. Tropical is the default, which is mostly used in Europe/USA. The sidereal option is used for Vedic charts – mostly used in India, but not exclusively. Please note that the last two sentences do not reflect the complicated/contentious choice of a zodiac by astrologers!

• Once this setting is changed eg to Sidereal, all charts created will be for the Sidereal zodiac.
• All charts incl Tropical charts edited and saved will then be Sidereal.

To change the currently viewed chart to sidereal:

1. Tap Sidereal on the Zodiac Settings – see screenshot above. Exit settings.
2. Go to Options and tap Edit Chart, and then tap Save – see screenshots below. All done.

Ayanamsha

Ayanamsha table

Example Natal Chart – Albert Einstein

Einstein Sidereal Natal

if you haven’t named your charts either tropical or sidereal as in the above chart which is named Albert Einstein – Sidereal, how to recognise if a chart is tropical or sidereal?

Look to the top right, if it doesn’t say Tropical then it’s Sidereal. You’ll see an ayanamsha if it’s sidereal. In this case Fagan/Bradley.

Filter Your Charts
