Erhöhte Sonnenaktivität (6. und 7. September 2011)

STRONG SOLAR ACTIVITY: Sunspot 1283 is crackling with solar flares. Yesterday, Sept. 6th, the active region produced an M5.3-class eruption at 0150 UT followed by a X2.1-class event at 2220 UT. NASA's Solar Dynamics Observatory recorded this extreme UV flash from the X-flare:

The flares produced waves of ionization in Earth's upper atmosphere, briefly altering the propagation of low-frequency radio signals around our planet. Moreover, the two eruptions hurled clouds of plasma (CMEs) in our direction. CME impacts, geomagnetic storms and auroras are expected on Sept. 8-10. Stay tuned for updates.
