Satellites of Saturn
Abstract
P. Lamy and N. Mauron, Laboratoire d'Astronomie Spatiale, Marseilles, send the following precise measurements of 1980 S 10 (cf. IAUC 3463) with respect to the center and equatorial plane of Saturn: Mar. 15.9528 UT, +57".24 (east), -0".55 (south); 15.9851, +58".93, -0".38; 16.0236, +60".40, -0".37; 16.0892, +61".45, -0".57; 16.126, +61".65, -0".67. They also provide the measurements: 1966 S 2, Mar. 15.9851, 22".45 west; 1980 S 3, Mar. 16.126, 19".75 east. They add that orbital analysis shows that 1980 S 10 (= 1980 S 6: cf. IAUC 3483) leads Saturn IV (Dione) by 72o.0. 1980 S 13 could not be found on plates taken on Mar. 15.9528 and 16.962 on the assumption that it trails Saturn IV by 57o and was brighter than magnitude 18.
