Raphael’s Astronomical Ephemeris has been published each year since 1819. It is an invaluable tool for the astrologer as it can show at a glance a wide variety of astronomical information which the astrologer needs to construct a chart for any moment in the given year. It also serves as a ready reference when needed to quickly and easily determine planetary placements, aspects, retrograde motions, solar and lunar eclipses, lunar phases – exact to the minute, and much more. It is not always convenient to draw up a chart, or even to use a computerized astrology program, in order to quickly view the weeks and months ahead or just to know when the next full moon is. As a pocket reference, this is where Raphael’s Ephemeris comes into its own. If you are planning to travel or to enter into a financial contract, a quick glance will show when Mercury goes retrograde - periods when you would be ill-advised to do so. Once you have located general periods of favourable or unfavourable planetary circumstances using the ephemeris, you can then produce full charts to fine-tune your choice of opportune times.
