A1919+43

B. A. Cooke and M. J. Ricketts, X-Ray Astronomy Group, Leicester University, inform us that Ariel 5 observations around 3U 1921+43 have refined the position to within a 90-percent-confidence error box with coordinates (equinox 1950.0) R.A. = 19h19m48s, Decl. = +44o10'; 19h17m53s, +43o45'; 19h18m50s, +43o36'; 19h20m43s, +44o00'. The source is probably associated with Abell 2319, not CSVS 4693 (IAUC 2972). The x-ray flux is consistent with that in the 3U Catalogue and shows no sign of variability on timescales greater than a few days.
