   I have just confirmed the field on available materials.  It is now
clear that both candidates in Wyckoff and Wehinger (1979) PASP 91, 173
and in Duerbeck (1987) Space Sci. Rev. 45, 1 are incorrect quiescent
counterparts.  It seems most likely the eastern component (the brightest
of the three) of the successive three stars drawn just north of the stars
a and b in Wyckoff and Wehinger (1979) is the correct quiescent counterpart.
This identification would siginficantly reduce the previously supposed
outburst amplitude to about 9 mag (now acceptable for a recurrent nova!).
