Watch for significant earthquakes, eruptions, and severe weather for 8-10 days post-impact.
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.

ANOTHER X-FLARE: Earth-orbiting satellites have detected another strong flare from sunspot 1283. The X1.8-class event at 2238 UT on Sept. 7th produced a bright flash of extreme UV radiation and hurled an inky-dark plume of plasma into space.

This is the third significant flare from sunspot 1283 since Sept. 6th. All three eruptions propelled CMEs in the general direction of Earth. Not one of the CMEs, however, will hit our planet squarely. Glancing blows from the three clouds will commence sometime on Sept. 9th and continue through Sept. 11th, possibly sparking minor geomagnetic storms.
X-flares of Solar Cycle 24: There have been only a handful of X-flares since the beginning of new Solar Cycle 24. Here is a complete list so far, all in 2011: Feb. 15 (X2), March 9 (X1), Aug. 9 (X7), Sept. 6 (X2), Sept. 7 (X2). Before these five, the previous X-flare occured on Dec.14, 2006, (X1) during old Solar Cycle 23.
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.
