Vulcan Calculation
Contents
As Vulcan is a hypothetical planet, there is no officially accepted ephemeris for the calculation of its position. However, two of the more widely used methods of calculating its position have been included in Solar Fire, and it is possible to choose which of these methods you would like to be used whenever Vulcan’s position is calculated. The possible methods are:

L.H.Weston - Professor Weston produced a set of orbital parameters for Vulcan based on a number of supposed sightings during last century and early this century. This proposed orbit has Vulcan orbiting the Sun once every 19.5 days, and having a maximum orb of about 8° from the Sun, as observed from the Earth. The complete theory is published in the booklet “The Planet Vulcan”, published by the American Federation of Astrologers, Inc. |
• |
D.Baker - Dr Baker has documented a theory for Vulcan based on a quantum mechanical type of behaviour. When Mercury is more than 3° from the Sun, then Vulcan is on the same side of the Sun as Mercury, and 3° from the Sun. When Mercury is within 3° of the Sun, then Vulcan is conjunct the Sun. The full rationale behind this concept is explained in his Dictionary of Astrology. |

Select one of the “Vulcan Calculation“ options from the “Options“ menu.
A tick appears to the left of whichever option is currently selected. Any charts which are subsequently calculated will use the newly selected calculation method.
