HD 88021/2 (ADS 7662) is a very close visual binary. The accepted visual orbit, which is of very high eccentricity and graded “reliable”, led to the expectation of a periastron passage in 1981, when there should have been a large difference in radial velocity between the components. No such event took place, and there is little indication that it is likely to occur in the near future. A new interpretation of the visual orbital data leads to an orbit of a different character from those hitherto proposed. A decision between the competing orbits should be possible within a very few years. Meanwhile, the method of spectral subtraction developed in Paper 1 has enabled us to separate the spectra of the two components and to show that their spectral types are K0 III and A2m.

Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
