My two recent H_alpha photometry observations (below) are consistent with spectra, in that, H alpha is in strong emission. Other novae and normal star H alpha photometry is at http://members.aol.com/dwest61506/page35.html. When the H alpha magnitude is less than 1.9 this indicates H alpha emission.
