S a sequel to the Ephemeris
X ( in CMO #344), we here list the necessary
elements of the Ephemeris for the physical observation of Mars from 1 July to
The data are listed for every day at 00:00
GMT (not TDT). ω and φ denote the longitude
and latitude of the sub-Earth point respectively. The symbols λ, δ
and ι stand for the areocentric longitude of the Sun, the apparent
diameter and the phase angle respectively. From this apparition, we have also
added the column of the Position Angle Π of the axis rotation, measured eastwards from the north point: This is
useful to determine the north pole direction from the pß. The apparent declination D of the planet is also given at the final column. The data here are
basically based on The Astronomical Almanac for the Year 2008.
