Abstract
Observations of the brightness and polarization of μ CEP over 1983-2002 are presented. An almost sinusoidal curve with a slightly varying amplitude and a period of about 850 days was fit to the light curve. The minima in the actual light curve often appear to be “flooded” with additional radiation compared to the smoothed curve. As an explanation of this phenomenon, we propose a working hypothesis whereby some radiation that is reflected back into the atmosphere near the equator through “veiling” by titanium oxide then partially diffuses into the near-polar regions where it escapes.
