Summary:
Active region 11043 rotated of the sun's visible disk.
Active region 11044 remained spotless and will rotate out of view by tomorrow.
Active region P100205a went spotless again, and again produced a little sunspot again
Active region 11045 continued its impressive growth. It has a beta-gamma magnetic configuration, and there are signs of a delta configuration. The region produced seven C-class flares and two M-class flares of which one was accompanied by again a strong radio burst, which was observed on HF bands. Also a ne CME was observed, and is likely to hit Earth within a few days. Region 11045 has grown into the most active region since the start of Solar Cycle 24, and there is no sign of any decay. It is the first active region in years to push solar activity to an official "high" level.
Active region P100207 was renumbered 11046 after being spotted by SEC. The region looks quiet and stable and has a beta type magnetic configuration, and a few sunspots.
New active region P100208 rotated onto the visible disk in the sun's southeast quadrant. The active region is a beta type and has one single sunspot.
On the sun's backside are currently three active regions. One of these active regions in the sun's northern hemisphere, is 4-5 days away from rotating into view,
The X-ray background radiation was around B7 level. Solar Flux at 1800 UTC measured 95.5, with a fair chance to increase as regions 11046 and P100208 turn into an Earth effective position. The geomagnetic field was quiet, and is expected to increase from active to major storm levels in the next 48 hours, as a CME and a coronal stream from CH390 hit Earth's atmosphere. These conditions may continue until Wednesday.
| Active regions visible | : 11044, 11045, P100205a, 11046, P100208 |
| Active regions not visible | : 3 |
| Solar Flux | : 95.5 |
| Sunspots visible | : 24 |
| Solar Flares | : multiple C, M3, M2 |
| Coronal Mass Ejections | : expected 9th February and 11th February |
| Coronal Holes | : CH390 |
| Geomagnetic field | : quiet (K2) |
| Solar Activity | : high |
Propagation : generally degrading conditions expected in the next 48 hours due to the arrival of a CME and coronal stream.
>2000km is poor, and above normal levels due to a quiet geomagnetic field. Northern hemisphere will experience best conditions because of seasonal influences, with propagation at lower and middle latitudes occasionally stretching out into higher latitudes. Southern hemisphere can expect propagation at middle and lower latitudes only. Propagation degrading at high latitudes with a good chance for Aurora propagation at the higher latitudes.
<2000km is poor. Occasional E-skip at equatorial, lower and mid latitudes. Daily weak to moderate E-skip in southern hemisphere peaking late local morning and late local evening. Occasional weak E-skip in northern hemisphere.
