New Horizon's ground track

The red curve is for the opening of the two-hour launch window, at 18:24 UT.
The yellow curve is for a mid point launch, at 19:25 UT.
The pink curve is for a launch at 20:23 UT, at the close of the launch window.

When the 2nd and 3rd stages of the rocket ignite to propel the spacecraft from the circular parking orbit, it should be possible to see it with binoculars from some islands in the Indian Ocean.
The 2nd and 3rd stage burns will be visible very low in the eastern sky as seen from Mauritius and the Indian Ocean region.
The 3rd stage burn may occur at 19:06 UT over the Indian Ocean if the spacecraft is launched at 18;24 UT; the 2nd-stage burn will be 5 - 2 minutes earlier, so observers in the Indian Ocean region should start observing by 19:00 UT.

New Horizons is set to lift off from Cape Canaveral, Florida, at 18:24 GMT on Tuesday aboard an Atlas 5 rocket.
Despite being the fastest probe ever built, it will still take more than nine years to reach Pluto.

New Horizons, aboard the Atlas 5, will be the fastest spacecraft ever launched, reaching lunar orbit distance in just nine hours and passing Jupiter 13 months later.
