According to Capaccioli et al, 1990, ApJ 360, 63, only _one_ observation was reported for this object in IAUC 2353, and it's not clear whether a good position exists.  SIMBAD quotes a good position and gives a source for that position which hints of problems.

So there's no real strong meaning or certainty of existance/type for that object, then?

Kind of important if we're thinking recurrence.

A. Subramaniam - G. C. Anupama 2002, A&A 390, 449 are quoted in SIMBAD for the accurate looking position therein, and they do carry a goodly position, but this latter paper quotes the above 1990 paper for this object, which doesn't give such a precise position at all.  In fact it gives an imprecise 1950s position that they could likely just have published after converting to J2000 without consideration of carrying the sig figs through from source to result.

This sort of thing happens so much when literature is traced back that it almost makes yer teeth hurt.

The table in this paper probably reflects the known precision of NOVA LMC 1971 b :-

There's no hint of spectroscopic confirmation for the 1971 object yet, and it looks certain it couldn't be confirmed by lightcurve decay profile.

Just about everything bar IAUC 2353 is available online in one form or another.

Cheers
