For 19 lunar and planetary conjunctions and occultations (occ.) with Nandou stars (1st, 2nd, ...) recorded in the Jin shu for the Jin dynasty (AD 265-420), cited after the English translation with commentary by Ho (1966), the star identification (ID) within Nandou (in Sgr) as given therein (following modern counting of star numbers) is listed, then the stellar identification of the historical observation for the closest conjunction as determined with Stellarium version 0.18.1 and confirmed with JPL ephemeries (using ΔT from Morrison & Stephenson 2004); dates and times given in Local Time (LT) for the Jin dynasty capital Jiankang, now Nanjing, China, 7:55h east of UT (Chinese records give the date of the evening for the whole night). Always, the closest conjunction with a Nandou star in the recorded night is considered, or otherwise the closest conjunction with a Nandou star within a few nights (Sep. for separation). In sum, this study of the reported conjunctions yields a fully consistent numbering of the Nandou stars, which can therefore be accepted as historical counting: 1st – ζ, 2nd – τ, 3rd – σ, 4th – ϕ, 5th – λ Sgr. However, the identifications in Ho (1966) never follow the observations.

The following conditions are employed: The observed conjunctions have to be at least 5° above horizon at darkness, i.e. when the Sun is at least 18° below horizon. If the closest conjunction is at day-time or below horizon, we list the next closest that fulfills the conditions for observability.

For completeness, there was also an occultation of σ Sgr on June 10 at 4:23h shortly after moon-set.

Closest conjunction was less than one hour after Venus had set; a close conjunction as reported was visible the hours before.

On that day, it was the Moon, not Venus, trespassing against τ Sgr.

Also a close conjunction with τ Sgr on Apr 11 visible at darkness above horizon at 4:22h with 77’ separation.

Here, the date in Jin shu is off by some 2.5 weeks.

On 404 June 9, the Sun was at −15°, on 410 May 6 at −6° altitude, both in the NE during the closest lunar conjunction in the SW.

Here, two observations seem to have been mistakenly merged into one: On the given date, Jul 27, Mars was in conjunction with δ Sco, while a close conjunction of Mars with λ Sgr was on Sep 18 of the same year; no conjunction with τ Sgr that year.

During the close conjunction of τ Sgr on June 23 at 20:17h, the Sun was 13° below horizon in the W; during daytime at 11:42h (below horizon), there was an occultation of ϕ Sgr by the moon.

Of the seven conjunctions described with ‘concealed’ (AD 265-420), six were very close encounters (or even occultations) between Moon and a Nandou star, one was the closest planetary conjunction (Mars, 3′).
