The continuum in my spectrum from last night does indeed match an A0v star which by definition has B=V=R
And in case anyone is wondering why a black body curve of ~15000K matches an A0V star visible spectrum when the effective temperature Teff you see in text books is 9500K this Wikipedia graphic explains it nicely
