Observers are encouraged to download and install the Occult software program to generate predictions for their own particular site coordinates. Occult will generate stars fainter than what are shown here, which can be suited to the size of your telescope. The Occult software includes a tutorial on getting it set up for your location and how to generate your first set of predictions.
A PDF file written by David Dunhams about the Occult predictions and software can also give added information.
The world map is a Mercator projection showing the basic circumstances of an occultation:
Where a line represent a feature of the event is located in the polar
regions, remember that the Mercator projection gives rise to serious distortions
in polar regions. Predictions and world path maps were generated using Occult v4.12.14.0 You are encouraged to generate predictions for your own site coordinates with many more fainter occultations, by downloading the free Occult software for your own use. After installation, there is a tutorial in the program which will guide you through the fundamental operations. Note: Cities will be prefixed with their 2 letter country code. Those for the United States will also include the 2 letter state code after the city. For a complete listing of the 2 letter country codes used in the predictions please download this PDF file for reference.
