Current Gray-Line Position on Earth

Gray-line Importance to Propagation Special ionospheric propagation conditions often exist between two or more stations simultaneously located on the gray-line transition between daylight and darkness. The current gray-line position is depicted on this topographical world map. (Allow a few seconds for current-position calculations, image creation, and image loading.)
