As we've probably said before, it's NSV 10892, spectral class "G", and a
ROSAT bright xray source.

So yes maybe EW.

When checking 55 matches of CD 23 against RASS BSC and 111 of RASS FSC
(faint sources) a not inconsiderable number turned out to be yellowish
stars between about mag 9 and 11 or so with Welch-Stetson indices over
1.

I think Tom's invented an EW detector.
