Ephemeris Overview for the year 2020, by JJ F1EHN
▪
Vertical grey bars show the days where the sky temp is high and could degrade
the system temperature.
▪ Vertical orange bars show the days where the moon is close to the sun (<10°).
Near the new moon dates.
▪ Extra-loss is the range extra-loss in dB compared to the minimum pathloss at
Moon perigee
▪ The WE dates are displayed at the top of ephemeris
graph. The declination is plotted as red curve and
extraloss as blue curve.
▪ Computations were done with EME System V7 – Planner module. Data printed by
F1EHN.
