Each year IOTA provides predictions for the circumstances of stellar occultations by the major planets and their satellites. David Dunham, using David Herald’s Occult program, has generated a listing of all the major planets and their satellites which occult stars in 2023.
A document with links to 2023 predictions is here.
Using the Occult program is explained here. In that explanation, there is reference to a file All2023.xml, a more comprehensive file that also includes occultations by asteroids as well as by the major planets. For predictions of just the major planets and their satellites, use the file Planets2023.xml instead of All2023.xml.
Additional information about occultations by major planets and their satellites, mainly for North America, is in the RASC Observer’s Handbook 2023.
