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 northern 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 Temperature 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 be up to 200K.
This can cause up to 8dB extra losses on RX at a good station.
