Larionov and L.Larionova from St.Petersburg University (Russia)\n<vml@VL1104.spb.edu>, <vlar@nm.ru> report:\n\nWe imaged GRB20060218 with 70-cm telescope of Crimean Astrophysical\nobservatory (Ukraine) and ST-7 camera of St.Petersburg University\nin photometric and polarimetric mode. Observations were made in R band from \nFebruary 20.17 to February 23.18. The rate of brightening in this period was \n0.18 mag/day. The polarization reached maximum of 6% on February 21\nand decreased to 3% on February 23. The positional angle remained \npractically unchanged, 110+\\-5 deg. The high and variable polarization\ngives evidence of strongly aspherical or non-thermal component in\nGRB20060218/SN2006aj radiation.\n\nThis message is citeable.",
