NOTICE: This will be the last year that I produce worldwide bright star occultations. I have been providing this service for 25+ years, spending countless hours each year. The process involves running the predictions, putting them into a spreadsheet, sorting and eliminating events which are either in very sparse locations, too close to the sun, or over oceans. I manually input the resulting data into this page, and then manually produce the corresponding prediction page. It is time to retire this method. Nothing more can be gained scientifically from observing these bright star occultations, and are more "eye candy" than anything else. I therefore am going to try on a trial basis, produce predictions for individuals who request them and email those predictions to them. In order to do this I need three pieces of information: your longitude and latitude; the size of telescope you will be using, and your experience level. This will give you much more accurate times for events and produce fainter occultations for you to observe and report. You can email your request to: webmaster at lunar-occultations dot com. Depending on how many requests I receive, will depend on whether I will continue this method. You are encourage to download and install the free OCCULT software to produce your own local predictions. I wish to thank all those who supported me in this effort, found errors to correct, and provided events I missed. - Rob Robinson, VP of Occultation Services
Observers are encouraged to download and install the Occult4 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 Dunham 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 v4.2024.x.x 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.
