Long-duration M2.0 solar flare erupts on the NW side of the Sun

A long-duration solar flare measuring M2.0 erupted from AR 2891, currently located on the Sun's northwestern limb. The event started at 15:47, peaked at 17:02 and ended at 17:37 UTC.

The location of this region does not favor Earth-directed CMEs. However, a proton solar radiation storm is possible.

Other than this, solar activity was low over the past 24+ hours and is expected to remain at very low levels, with a chance for C-class flares through November 11, mainly due to the flaring potential of Regions 2894 and 2895.1

The greater than 2 MeV electron flux reached high levels with a peak flux of 3 319 pfu observed at 18:50 UTC on November 7 and is expected to be at moderate to high levels through November 11. The greater than 10 proton flux is expected to remain near background levels during the same period.

The solar wind environment was at or near background levels and these levels are expected to persist through November 11.

The geomagnetic field is expected to be mostly quiet, with a chance for isolated unsettled periods.
