English: This file shows the path on the Earth's surface within which it is predicted to be able to see the occultation of Regulus by asteroid (163) Erigone. The outer lines represent the 1-sigma uncertainty boundaries - i.e., the area in which there is a 66% chance that the entire shadow will be found. This map is one of hundreds that Preston makes available as part of the International Occultation Timing Association goal of publishing predictions of asteroid occultations.
