2 It occurs to the Meetings Recorder that if the outburst behaviour observed in the V-band were explained by a sudden infall of material onto the magnetic poles of the white dwarf, then, if this material were to be falling preferentially (or exclusively) onto one of the poles, the observed periodicity seen at such wavelengths during outburst would also be explained. This hypothesis could be tested either by multi-waveband concurrent observations, or, more accessibly to amateurs, by a detailed V-band study during quiescence, accumulating sufficient data to statistically prove or refute the presence of modulation at the first harmonic of the spin rate outside outburst.
