EARTH-DIRECTED FLARE: This morning at 0150 UT, sunspot 1283 produced an M5.3-class solar flare. A movie from NASA's Solar Dynamics Observatory shows the flash of extreme UV radiation. Because of the sunspot's central location on the solar disk, the eruption was Earth-directed and a CME might be heading our way. Stay tuned for updates.

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 general direction. A preliminary analysis of SOHO and STEREO imagery suggests that the CMEs could sail substantially north of Earth, delivering a glancing blow to Earth's magnetic field as they pass. ETA: Sept. 8-10. Stay tuned for updates

NOTHER 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. Click to view the movie from NASA's Solar Dynamics Observatory:

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.

Mega quakes occur more frequently when sun has fewer sunspots: researchers

The frequency of mega earthquakes increases during periods when the sun has fewer sunspots, a team of Japanese researchers has found.

The finding was made by a team led by Kiyofumi Yumoto, a researcher in space and earth electromagnetism at Kyushu University's Space Environment Research Center.

The March 11 Great East Japan Earthquake occurred when there were few sunspots. The latest research suggests that the sun's activity could influence movements beneath the earth's surface.

Sunspots gradually increase and decrease in number in a cycle of about 11 years, and cause changes in the earth's atmosphere. The research team investigated the possibility that they could also produce changes beneath the earth's surface, and compared data on the number of sunspots between 1963 and 2000 and the 327,625 earthquakes of magnitude 4 or more that occurred during this period.

The study found that 65 percent of the earthquakes with magnitudes between 4.0 and 4.9 occurred during the periods with the fewest sunspots (each lasting about two years). The figure was around the same for earthquakes with magnitudes between 5.0 and 7.9. However, the figure was higher for the 28 mega earthquakes with magnitudes in the 8.0-9.9 range, with 79 percent of them occurring during periods with the fewest sunspots.

When there are fewer sunspots, a phenomenon occurs in which solar winds, or streams of charged particles from the sun, get stronger an average of three to four times a month. Seventy percent of the earthquakes of magnitude 6.0 or stronger occurred at such times.

Solar winds that become stormy are known to be able to induce strong currents in power transmission lines, which can lead to major blackouts.

"The relationship between the sun and the activity of earthquakes is not clear, but we hope that this is a step in uncovering the mystery of quakes," Yumoto said.

The results of the group's research will be announced at a meeting of the Society of Geomagnitism and Earth, Planetary and Space Sciences, which opens in Kobe on Nov. 3.
