COMING 2001 MARS (08)


Ephemeris for Observations of Mars in 2001 ( III )

Akinori NISHITA


    The following is an Ephemeris useful for the observation of Mars in April and May 2001, and makes a sequel to the Table in #238 p2868. The data are listed for every day at 00:00 GMT (not TDT!).

  LCM and De stand for the longitude and the latitude of the sub-Earth point, Ls for the areocentric solar longitude, diam for the apparent diameter of the disk in arc sec, and i for the phase angle. We use i to indicate how far the noon line is separated from the CM (not exactly however). The phase is given by the formula ( 1+cos i )/2.
