Stationary occultations from low Earth orbit

The process of stationary lunar occultations is considered for observers in low Earth orbit. The orbit of the Hubble Space Telescope (HST) is used as a prototype. The noncoplanarity of the HST and lunar orbits disrupts many of the expected stationary events, and orbital drag complicates the prediction problem. In a typical year, the apparent speed of the lunar limb s e e n b y the HST is slower than a typical groundbased event only about 0.7% of the time. The orbit prediction can be wrong by a
