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.       http://www.F1EHN.org
