(911) AGAMEMNON, 1919 FD.
This planet was discovered by Reinmuth' at Heidelberg on March 19, 1919.
The nature of its motion (Jupiter group) was noted about the same time by Palisa and Berberich.2 The preliminary elements A by Berberich are published in A. N. Vol. 208, p. 332. A comparison between computation and observations for 1919 May 20, gives Δα = -4 Δδ = -2.
Elements A are brought forward to mean equinox of 1925.0 and with an ephemeris are published in Kleine Planeten for 1920, p. 25 and p. 47.
An observation on March 11, 1920, gives a correction to the ephemeris of +1m.5 in right ascension and -18' in declination. An ephemeris for 1921 is given in Kleine Planeten for 1921, p. 20.
