PERIODIC COMET SWIFT-GEHRELS (1981j)
This comet has been recovered by C.-Y. Shao and G. Schwartz on
exposures with the 1.5-m reflector at the Oak Ridge Observatory:
1981 UT R. A. (1950) Decl. m2
July 31.26675 22 43 50.46 - 4 41 57.5 18.5
Aug. 1.23275 22 43 44.48 - 4 33 17.4
2.28005 22 43 35.89 - 4 23 51.7
The object is essentially stellar in appearance. The indicated correction
to the prediction on MPC 5656 (elements on MPC 5638) is Delta-T =
+0.21 day, and the epherneris is revised as follows:
