    4.66 4.84 4.76 5.03 4.92 4.05 sec.
    A lot of scatter in the timings.
    Bjorn pointed out that my obs of March 30 has a better fit with a
    period of 4.72 sec, 0.06 lower.
    I used Synodic on todays obs and 4.70 sec gives the best fit.
    So it seems that the period is still decreasing.
