15 February

Solar wind speed, as measured at the ACE spacecraft, reflected nominal
conditions varying between approximately 330 km/s to 370 km/s. IMF total
field was steady between 5 nT and 7 nT for the majority of the period
with only a short dip to 2-3 nT from 14/1300-1400 UTC. Bz was
predominately north throughout the period with some southward incursions
to -3 nT between 15/0005-0217 UTC. The Phi angle began the period in a
negative (towards) orientation through 15/1335 UTC when a switch to
positive (away) was observed for the remainder of the period. Low energy
particles indicated a slow rise through about 15/0900 UTC when a sharper
increase in values was observed.
