| Description | The ephemeris of variations of the cool magnetic CP star HD188041 was newly determined using all photometric, magnetic and spectroscopic observations available. The improved period P=(223.826+-0.040)d is common for all type of variations observed, the other ever mentioned periods were definitely eliminated. The origin of phase counting M0 = 2,444,981.8+-0.6 was put in the center of v light minimum. The effective magnetic field maximum lies at the phase 0.002+-0.019. The slightly asymmetric curve of Gd II line intensity has its maximum at -0.031+-0.012. |
