iOS Ephemeris

The Ephemeris displays standard monthly tables of Longitude as well as Moon phases and Eclipses.

• Ephemeris tables display a full month of Planetary, Lunar Phase and Eclipse data.
• Positions (longitude) are Tropical or Sidereal as per Settings.
• Data is grouped into weeks.
• The GST column displays Greenwich Sidereal Time.
• Two Moon columns are included:
  • The first displays Lunar position at Ephemeris Time as set in Preferences.
  • The second displays the position 12 hours later.
• Columns for any body can be turned on or off in Settings. The Ephemeris and Dec/Lat tables share settings, i.e. changes on either view effect the other.
• Planetary longitude data is read as follows:
  • DMS: 11!45″R = 11 degrees, 9 minutes 45 seconds, in the sign of Aries. The Planet is Retrograde.
  • DM: 12+1.9 = 11 degrees, 1.9 minutes in the sign of Aquarius.
