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.
SOLAR RADIO BURSTS: This week's sharp increase in solar activity has turned the sun into a radio transmitter. Bursts of shortwave static are coming from the unstable magnetic canopy of sunspot 1283.
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.
Editor's note: Brace yourself for significant earthquakes, eruptions, and severe weather for 8-10 days post-impact.
