Plotting the Path on Maps

For high resolution maps of the umbral path, the coordinates listed in Tables 7 through 10 are conveniently provided in longitude increments of 30' to assist plotting by hand. The coordinates in Table 3 define a line of maximum eclipse at five minute increments. If observations are to be made near the limits, then the grazing eclipse zones tabulated in Tables 9 and 10 should be used. A higher resolution table of graze zone coordinates at longitude increments of 7.5' is available via a special 2002 eclipse web site. Global Navigation Charts (1:5,000,000), Operational Navigation Charts (scale 1:1,000,000) and Tactical Pilotage Charts (1:500,000) of the world are published by the Federal Aviation Agency's National Aeronautical Charting Office (NACO). Sales and distribution of these maps is through the NACO For specific information about map availability, purchase prices, and ordering instructions, contact the NOS at:
