This data set consists of preliminary solar wind parameters presented in the monthly publication "Solar-Geophysical Data" issued by the NOAA Environmental Research Laboratories. These parameters are determined by measurements on the Pioneer 6 and 7 space probes. The information given consists of date, time, spacecraft, pass number, bulk velocity, and corotation delay time. The bulk velocity is accurate to 10%. The corotation delay time is the number of days between the observation at the spacecraft and the subsequent observation at the earth of the corotating interplanetary magnetic flux tube (assuming that the solar wind speed reported remains constant). Typically, there is one velocity value given for each satellite per day. On about 30% of the days, no data are given. There is a 1-month lag between the time the data are acquired and the time the data are published.
