Scientific paper

Observations covering a period of 20 years show that the large proper motion (4.08 arc sec yr-1) of the nearby triple system 40 Eridani-ABC will cause its brightest member, A, to pass within 3arcsec of a faint background star. The originally hoped-for primary gravitational lens effect will therefore not take place although a minor secondary effect may occur near the time of closest approach on 1987 June 1.
