R. S. Harrlngton, U.S. Naval Observatory, writes that analysis of exposures on Apr. 13 and 20 by C. C. Dahn and J. W. Christy with the 1.5-m reflector and 0.2-m astrograph indicates that at the time of the observed occultation associated with Pluto on Apr. 6 (cf IAUC 3466) the star was ~ 0".5 west and 0".9 north of Pluto. 1978 P 1 was predicted to be 0".1 west and 0".9 north, supporting the conclusion that the occultation was caused by the satellite.
