8th October

Solar wind conditions were largely nominal for most of the period until
a solar sector change to a positive phi orientation change completed at
around 08/0600 UTC. Shortly after, Bt increased from an average between
4nT and 5nT to steady near 9nT. Bz displaced to -8nT, where it remains.
No SWEPAM signatures were noted. Solar wind speeds remained steady near
360 km/s over the period.
