STEPHENSON 557
     P. Pesch, Warner and Swasey Observatory, reports that C. B.
Stephenson and N. Sanduleak have identified the long-period variable
(Kuwano's "possible nova") in Scutum (IAUC 2978) with No. 557
in the General Catalogue of S Stars (Stephenson 1976, Publ. Warner
and Swasey Obs. 2, 21), where its position is given as R.A. =
18h24m07s.9, Decl. = -14o43'38" (equinox 1950.0).  They confirm the
star's variability.  An objective-prism plate (dispersion 280 A/mm)
obtained with the Burrell Schmidt telescope on July 22 UT by
Stephenson and P. Chen shows the star near the plate limit at blue
magnitude ~ 13; the star is somewhat reddened and exhibits fairly
narrow H-beta and H-gamma emission.


1973 EA
     The following precise positions have been reported:

     1975/76 UT          R. A. (1950) Decl.        Observer
