ATP=ActivityTimePeriod for 432MHz, see homepage of SM2CEW or EME pages send reports to K2UYH & Dubus,

432 MHz activity times should boost the 432MHz CW EME activity. See some big guns in CW within 432.010 and 432.050 MHz.

 

High positive Declination shows that the moon transit is in the norther hemisphere, red negative Decl indicates a southern transit of the moon.

Loss in dB indicates the extra losses due to the different distance earth-moon, best case at perigee is +0,3dB and worst case at apogee -2dB.

The background TEMPeratue indicates the losses caused by the noise from objects behind/near the moon. Coldest value on 432 is 15K and when the moon is in front of our galactical centre this value can up top 200K. This can cause up to 4dB extra losses on RX at a good station

 

More detailed info can be taken from VK3UM(sk) famous EME Planner

Sat = Saturday, sun = Sunday, all times in GMT/UT

Nice view of the earth from moon on G4ZTR pages see here

More 432 & up EME news and hints can be found on http://www.moonbouncers.org/

Details about expeditions are here

A good contest overview you can find at WA7BNM

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
