Solar activity remained at low levels throughout the
reporting period, with only about ten low-intensity C-class flares observed.
Most of these flares originated from a newly emerged active region near the
southwest limb early in the week. NOAA designated this region as AR 14561, and
it rotated onto the far side of the Sun on October 28 after crossing the west
limb. The region produced the strongest event of the week, a C2.8 flare on
October 26. None of the flares were associated with Earth-directed CMEs. However,
a filament eruption on the visible disk generated a CME that resulted in a
glancing geomagnetic impact at Earth, producing auroral activity on October
30-31.
The latest helioseismic maps reveal a small number of active
regions on the Sun's far side. If these regions persist, some may rotate into
the Earth-facing hemisphere towards the end of the week.
