>Hoping to bridge the two, does anyone have a recent elset for the Hubble >Space Telescope? What is its magnitude? 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.
