Scientific paper

The Solar Wind Around Pluto (SWAP) instrument aboard the NASA New Horizons spacecraft measured ions from ~11.2 to ~11.8 AU in the ecliptic plane in late 2008. We analyze about 25 one day (nominally) integrations of the combined distribution function of these ions from ~20 eV/e to 7.5 keV/e. In conjunction with these histograms, we report statistics on pseudo-moments computed for each hour. This auxiliary data provides a measure of the variability of the solar wind during the integration time of the histograms. Initial results indicate that the variability in the bulk speed appears to widen the histogram distribution, which artificially increases temperatures estimated from the histograms. In general, the pickup ions appear to be highly organized by the bulk solar wind speed, consistent with previous reports; however, there is a great deal of variability between these histograms. We intend to search for factors that will order this variability such as stream structure in the solar wind.
