Amateurs interested in timing these occultations can make real contributions to science. (See How and Why to Make Occultation Timings.) But first you have to know what occultations will occur in your area.
You can find many occultation predictions at the International Occultation Timing Association’s site, www.lunar-occultations.com/iota. There you can also download the free Occult program to create full, detailed predictions for your exact location.
The main page (with links to predictions, observing methods, reporting, and past results) is at www.asteroidoccultation.com/observations.
Go to iota.jhuapl.edu/timng920.htm.
Lots about observing occultations of every type is in Chasing the Shadow: The IOTA Occultation Observer’s Manual, available free at www.poyntsource.com/IOTAmanual/Preview.htm.
