There are currently two numbered regions on the visible disk, AR2778(S18W67) and AR2779(S15W58). No earthbound CMEs were observed in the available imagery. Solar activity is expected to be low for the next three UT days, 31 October to 02 November with a slight chance for an isolated M-class flare. On UT day 30 October, the solar wind was slightly enhanced, between 400-450Km/s due to the influence of a north polar coronal hole extension. The total IMF (Bt) was weak, under 5 nT and the north-south component of the IMF (Bz) was mostly neutral. The solar wind speed is expected to be near its nominal levels for the next three UT days, 31 October to 02 November.
