Seeing Double And Even Triple On Jupiter

Sometimes the shadows cast by Jupiter's satellites on the face of the planet during transit are doubled or, more rarely, tripled. This article draws attention to several recent observations of this most perplexing phenomenon. W.E. Fox points out that these multiple shadows are really not all that uncommon. He does not try to explain them.

(Fox, W.E.; "Jupiter: Double and Triple Satellite Phenomena," British Astronomical Association, Journal, 88:360, 1978.)

Reference. Our Catalog, The Moon and the Planets, records several observations of double shadows in Section AJX. For a description of this book, visit: here.
