Solar wind was nominal during the day. Solar wind velocity was steady
near 325 km/s for the first half of the period, but decreased sharply at
approximately 0200 UTC. With fluctuations between 254 km/s and 330
km/s, the second half of the period ended near 270 km/s. The total field
ranged from 1-3 nT and the southward component of the interplanetary
magnetic field fluctuated between +/-2 nT. The Phi angle remained
predominantly in a negative (towards) sector with brief interludes into
the positive (towards) sector.
