.24 hr Summary...
Solar activity reached low levels due to a C1/Sf at 10/1522 UTC from
Region 2497 (N13E08, Eac/beta-gamma). Region 2497 grew further in size
and maintained a weak intermixing of polarities amongst the intermediate
spots, however the associated areas of magnetic shear were small and
appeared minor. The region also produced a few B-class and optical
flares. Region 2494 (S12W70, Dso/beta) decayed further and was inactive.
The remaining three spotted regions were inactive and underwent some
decay. No Earth-directed CMEs were observed in available coronagraph
imagery.
.Forecast...
Solar activity is expected to continue at very low levels with C-class
flares likely on days one and two (11-12 Feb), decreasing to a chance
for C-class flares on day three (13 Feb). Region 2497 is likely to be
the primary contributor. Region 2494 will rotate to and beyond the W
limb on days two into three (12-13 Feb), allowing for decreasing
whole-disk flare probability; contingent upon no strengthening or
increased complexity within Region 2497.

.24 hr Summary...
The greater than 2 MeV electron flux was at normal to moderate levels
and the greater than 10 MeV proton flux remained at background.
.Forecast...
The greater than 2 MeV electron flux is expected to continue at normal
to moderate levels on day one (11 Feb), before decreasing to normal
levels on days two and three (12-13 Feb) as a CIR followed by a CH HSS
redistributes electrons. The greater than 10 MeV proton flux is expected
to continue at background levels all three days (11-13 Feb).
