Latest EME Propagation

CURRENT SOLAR FLUX / CURRENT SUNSPOT DATA / CURRENT MUF DATA ( useful info for calibrating EME receive systems in making sun noise measurements )

    

 

                 

        

                                  

 

Moon phase info is useful in giving an indication of how close the moon is in relation to the sun in time for viewing and locating purposes. This is especially useful for EME operators in trying to located the position of the moon in the sky. A small moon crescent phase will indicate that the moon is viewable within afew hours away from the sun. A full moon is approximately 12 hours from the sun and a new moon is viewable within the same time period as the sun. Moon phase has absolutely no influence on EME propagation or EME signal quality other than any solar or celestial noise ( such as the milky way and some star noise sources ) that is located behind and around the moon.
