    HST             13.3  4.3  0.0  3.0 v   71
    1 20580U 90037B   00066.66540525  .00005791  00000-0  57525-3 0  3015
    2 20580  28.4644 168.4790 0014658  96.6493 263.5762 14.89691643341102
    The magnitude depends partly on its distance to you and the
    sun-satellite-observer angle (i.e. how much of the satellite is being
    illuminated from your view point). Since Hubble is at a 28 degree
    inclination, the further north or south from the equator you are the more
    atmosphere you will be looking through when (if) you see it. If you are too
    far north or south on the earth (above or below 38 degrees N or S latitude)
    then you won't see it at all. The 3.0 in the top line of the elset means
    that at 90 degree sun-satellite-observer angle and a distance of 1000 km its
    magnitude will be 3.0. More illumination or closer equals brighter, reverse
    is also true.
