Around the time of polarity reversal in 2000 – 2001, the solar wind plasma parameters and interplanetary magnetic field fluctuations are studied for an interval of time that corresponds to Ulysses in-situ measurements of high-latitude heliospheric magnetic field. This study has been done by investigating solar wind speed, density, temperature and solar magnetic field using Ulysses magnetometer and SWOOPS instrument. The sun's magnetic field reverses polarity approximately in every 11 year and it creates a peak in each solar cycle. This study gives a brief understanding of solar wind parameters in the heliosphere during polar reversal in solar cycle 23. The solar magnetic field completely reorganizes during the polar reversal phase, hence the distribution of solar wind parameters changes accordingly. By studying the variation of solar wind parameters, it is possible to understand the polar reversal phenomenon. The photospheric polarity reversal is completed in more active Northern Hemisphere in late 2000 and then in the Southern Hemisphere in 2001. The reversal of the magnetic field at the solar wind source surface is inferred to have occurred between late 2000 and 2001, with the most likely time of reversal being early within that period.
