We have received the following telegram from Prof.
Shapley:
"Leuschner telegraphs preliminary investigation Lowell
observatory object by Bower and Whipple results in group
of solutions giving approximate present distance forty one
astronomical units inclination 17 deg. longitude node 109 deg.
Observations chiefly by Meyer Lick Observatory March 16th to
April 4th are accurately represented by orbits varying from
near circle to parabola with perihelion distance 17 astronomical
units."
An Observation Circular from the Lowell Observatory
of 1930 March 13 gives details about the search for a transneptunian
planet, the discovery of the new object on plates
of 1930 Jan. 21, 23 and 29 and about the observations since
that time.
