And John Greaves has found that the companion is also a variable star with a 
period of 19.2 days and an amplitude of 0.3 mag. Cepheid-like lightcurve 
contaminated by the mira. Maybe SRd or CW although a K spectral type found 
by Patrick in the literature makes me feel more comfortable with the SR 
possibility. But maybe the spectrum is contaminated by lines from the 
mira...
John suggests observations when U Men A (the mira) is at minimum.

Sebastian.
