Abstract
POSITIONS of the newly discovered Satellite X are available from July 6 to August 1, but the interval is too short for the computation of an orbit with any degree of certainty. A preliminary investigation, however, suggests that the object is at a distance of about 7 million miles from Jupiter, its motion being direct. Whether it is just inside the orbit of VI or outside that of VII is open to doubt, but further observations will enable computers to decide this point. Observations of Satellite XI are available from July 30 to August 1, but it is impossible to compute an orbit from such data. From the figures it is conjectured that the body cannot be less than 10 million miles from Jupiter, and so it certainly lies outside VII, but there is nothing at present to show that it does not lie outside IX.
