An exeligmos is a period of 54 years, 33 days that can be used to predict successive eclipses with similar properties and location. The paths shift north or south, depending on orbital geometry. There is exactly one for every three 18-year cycles within a saros. Below are examples of total eclipses that could potentially be visible to people alive today located in the US and/or adjacent countries or regions:

 

Saros 120
1979-02-26 US (Oregon-N.Dakota), Canada
2033-03-30 US (Alaska)

 

Saros 126
1990-07-22 US (Alaska)
2044-08-23 Canada, US (Montana-N.Dakota)

 

Saros 130
1998-02-26 Caribbean
2052-03-30 Mexico, US (Florida-S.Carolina)

 

Saros 136
1991-07-11 US (Hawaii), Mexico
2045-08-12 US (California-Florida), Caribbean
2099-09-14 Canada, US (N.Dakota-N.Carolina)

 

Saros 139
1970-03-07 Mexico, US (Florida-Virginia), Canada
2024-04-08 Mexico, US (Texas-Maine), Canada
2078-05-11 Mexico, US (Texas-N.Carolina)

 

Saros 145
1963-07-20  US (Alaska, Maine), Canada

Yes, I've seen one exeligmos (1963 in Quebec and 2017 in Oregon) and intend to see another (1979 in Washington state, 2015 over the North Atlantic by charter jet and 2033 in Alaska which will also be by charter jet).
