15th October


Solar wind parameters were consistent with coronal hole high speed stream (CH HSS) effects. Speeds remained fairly steady near 450 km/s the first half of the period while the IMF total field ranged between 13 and 3 nT. A subsequent increase in wind speed, density, and temperature at approximately 15/0110 UTC, followed by a slight decrease in temp and density, indicate the possible arrival of the anticipated 11 Oct CME. With only a slight disruption in the magnetic field, it appears to have been a weak CME with only minor impacts observed.
