NASA provides an interactive Google map showing the path of the Total Solar Eclipse of 2017 Aug 21. The northern and southern path limits are blue and the central line is red. You MUST be somewhere within the central path (between the blue lines) to see the total phase of the eclipse. The eclipse is longest on the central line (red). The yellow lines crossing the path indicate the time and position of maximum eclipse at 10-minute intervals.
You can be hundreds of miles from the theoretical point of Greatest Duration and still enjoy totality lasting within a fraction of a second of the maximum possible (as long as you stay within several miles of the central line). It’s much more important to watch the weather forecasts a day or two before the eclipse and choose a location with the best chance of a cloud-free sky during the eclipse. Even in Oregon, the total eclipse still lasts 2 minutes. Good weather is the key to successful eclipse viewing – better to see a shorter eclipse from clear sky that a longer eclipse under clouds.
