Dear Colleagues, for what is worth, I would like to point your attention to a quite interesting result. As I said, my latest photometry (a 6.5 hours long) gives, if considered alone, a period candidate of 0.057299d. Compared with the shorter, orbital period (0.05669d), I have a difference of about 1 percent, not so different from what reported by Patterson et al. during the 1978 outburst (0.8 percent). Just a coincidence? Time will says us!
