Abstract:
The ephemeris of variations of the cool magnetic CP star HD 188041
was newly determined using all photometric, magnetic and spectroscopic
observations available. The improved period
P=(223.826±0.040) d is common for all types of variation
observed, all previously mentioned periods were definitely eliminated. The
origin of phase counting
M0=(2 444 981.8±0.6) was put in the
centre of the v light minimum. The effective magnetic field maximum
lies at phase 0.002±0.019. The slightly asymmetric curve of
Gd II line strength has its maximum at -0.031±0.012.
