Although, the new sunspot 1427 poses no threat for strong flares, a solar wind stream flowing from a minor coronal hole could reach Earth on March 4-5.
NEW ACTIVE REGION: A new and active Sunspot is now rotating into view on the northeast limb. It produced a moderate M3.3 solar flare at 17:45 UTC on Friday afternoon. All of the other current regions have been stable since the C3.3 flare around 1423 on Thursday. SOLAR WIND INCREASE: The solar wind did show a gradual increase to near 550km/s on Thursday and combined with a predominantly south tilting Bz, it did trigger minor geomagnetic activity at very high latitudes. The Kp reached 4 at its peak. The increase in geomagnetic activity was most likely due to a solar sector boundary crossing. MODERATE SOLAR FLARE: A moderate solar flare reaching M3.3 took place at 17:46 UTC Friday afternoon around a new sunspot rotating into view on the northeast limb. - Solar Ham.
FIRST AURORAS OF MARCH: A magnetic disturbance rippled around the Arctic Circle during the waning hours of March 1st, sparking bright auroras just as night fell over northern Europe. "The show was stunning and amazing," says Thomas Albin, who sends this picture from Esrange, Sweden. "There were three different colors visible and the dynamics of the lights were incredible!" he says. A medium-speed solar wind stream is buffeting Earth's magnetic field. By itself, this was not enough to explain what happened. The extra ingrediant was the IMF: the interplanetary magnetic field near Earth tilted south, opening a crack in our planet's magnetosphere. Solar wind poured in and fueled the display. - Space Weather.
