    Hi to all. I am a little bit confused about this:
    Playing around with SatEvo and inputing various -F values, the result is: 
    the bigger the value (which means strongest solar activity), the decay time 
    moves later.
    But reading articles about space debris, the result of strong solar activity 
    is faster decay of the satellite.
    Does the height of the doomed satellite plays a vital role? One explanation 
    I thought is that when solar activity increases, the atmosphere expands and 
    affects the bodies in the higher orbits. Does this means that the atmosphere 
    density in the lower orbits drops thus the decay of these objects happens in 
    a later time? Is that right?
