    Hi!
    
    >Months ago, while reading old posts, I found a formula expressing satellite magnitude as a function of standard magnitude >and phase angle.

    See McCant formula:
    
    http://www.sat.belastro.net/appendix/m0_McCants.gif
    
    where "m0" -- standard magnitude, "m_r" -- magnitude at a moment, "r"
    -- distance to satellite, "psi" -- phase angle.
    
    Also you can use another formula:
    
    http://www.sat.belastro.net/appendix/m0_my.gif
    
    where "psi_0" = 90 deg., "r0" = 1000 km.
    
    These formulas absolutely identical.
