Scientific paper

Photometric observations of the asteroids 9 Metis, 18 Melpomene, 60 Echo, 116 Sirona, 230 Athamantis, 694 Ekard, and 1984 KD from October 1983 to June 1984 are reported. The following synodic rotational periods and amplitudes are reported: 9 Metis, P = 5.04 hr, delta M = 0.05; 18 Melpomene, P = 11.570 hr, delta M = 0.22; 60 Echo, P = 25.208 hr, delta M = 0.22; 116 Sirona, P = 12.028 hr, delta M = 0.42; 230 Athamantis, P = 23.99 hr, delta M over 0.20; 694 Ekard, P = 5.925 hr, delta M = 0.50; 1984 KD, P = 1.97 hr, delta M = 0.26. The rotational periods reported for 60 Echo, 116 Sirona, 694 Ekard, and 1984 KD represent completely new results. The period reported for 1984 KD is tentative.
