Abstract. A set of fourt large-scale exposures of comet Liller 1988 V taken between 1988 May 5 and May 10 is evaluated. The observations were obtained with 63/85/187 cm Maksutov telescope of the Klet' Observatory. The studies plasma tail is slightly fuzzy due to the projection on the dust tail. The length of the plasma tail on the best picture of May 7 is at least 1.5 degree. For this period the solar wind velocity was determined from the aberration angle of the plasma tail in the cometary environment. This value of the solar wind velocity is compared with the satellite data recorded near the Earth.
