It had been decreasing ~8 s annually, but the rate appears to have decreased considerably over the past year, so it may be approaching a minimum. I have plotted it with a linear fit and a 2nd order polynomial fit; I doubt there is any statistical significance, but the latter seems closer. Time will tell. http://satobs.org/seesat_ref/99028C_period_of_var/99028C_period_of_var_5a.pdf http://satobs.org/seesat_ref/99028C_period_of_var/99028C_period_of_var_5b.pdf Ted Molczan _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
