Bulletin

Solar activity was at very low levels, no significant flares have been recorded. The Sun remained spotless. No earth-directed coronal mass ejections (CMEs) have been observed in the available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal values.

Solar activity is expected to remain at very low levels.

The solar wind fluctuated around 385 km/s for most of the period and then began increasing, from 6 UT October 9, reaching up to 430 km/s (ACE). The total magnetic field fluctuated between 0 and 5 nT and then from 6 UT gradually increased to values up to 9 nT. Bz was mostly negative and varied between -7 and +3 nT.

Geomagnetic activity was quiet to unsettled for the first part of the period, following which active conditions were observed (Kp and local k index Dourbes = 4) between 9 and 12 UT October 9 due to an extended period of strong negative Bz.

Unsettled conditions are expected to continue with isolated active periods possible over the next 24 hours in response to further enhancements in the solar wind.
