It is shown that consideration of the $SLν$ in matter in hep-ph/0605114 is based on erroneous calculations which ignore the fact that the energy-momentum conservation law can not be violated for this process. An attempt to rename the $SLν$ in matter, undertaken in hep-ph/0606262, is groundless.6 pages, contribution to the Proceedings of the 14th International Seminar on High Energy Physics "Quarks-2006" (St.-Petersburg, Repino, May 19-25, 2006); v2: a typo correctedHigh Energy Physics - PhenomenologySpin light of neutrino in matter: a new type of electromagnetic radiationtext
