Description We critical analyze paper by V.A.Kotov [1], what contains the important results of observations of total magnetic field of the Sun observed in Crimea astrophysical observatory in FeI 5247.1 and 5250.2Å lines during 2001–2011. A conclusion is argued that obtained observational data indicate the true magnetic field changes in small-scale flux tubes. Likely, magnetic field strengths in such fluxtubes change with solar cycle phase in the following way: maximum field values arise nearly the minimum of sunspots number, whereas minimum one – 2–4 years after peak of solar cycle. From comparison of named changes with visual measurements of magnetic fields in sunspots [2, 3] follows that magnetic field strength in large sunspots (22–44 Mm) and spatially unresolved fluxtubes change in opposite phase with difference no more than one year.
