For the past some days our sun's AE 1504 has been erupting with consecutive CMEs towards space and our earth, ranging from class C1.0 to class M2.0 eruptions.
Today the previous class M1.9 eruption & class M1.2 CME is impacting earth's magnetosphere causing a mild to medium magnetic storm with some disturbance in satellite reception possible. Tonight's aurora should be splendid.
UPDATE: 10:00p.m Intitially the impact appeared to be weak, but now the effects are growing. Analysts at the Goddard Space Weather Lab say the impact strongly compressed Earth's magnetic field, directly exposing some geosynchronous satellites to solar wind plasma. Geomagnetic storms and auroras in the hours ahead.
Sunspot AR1504 has developed a 'beta-gamma-delta' magnetic field that harbors energy for strong solar flares--and the huge sunspot is directly facing Earth.
