Scientists have recorded a powerful M-class flare on the Sun

[Regnum] Scientists from the Institute of Applied Geophysics (IPG) recorded a powerful M-class flare on March 5 that lasted for nine minutes. This was reported by the press service of the institution.

“An M1.7 flare was recorded in the X-ray range in the sunspot group 4016 (S25E43),” the IPG website says.

Scientists assess the integrated solar activity as moderate. Also, 18 class C flares were registered in the X-ray range, and two subflares in the optical range.

Solar flares are divided into classes A, B, C, M and X depending on their power. At the lowest activity, equivalent to the radiation power in Earth orbit, they are assigned the index A0.0. The power between classes differs by a factor of 10.

As reported by the Regnum news agency, on February 28 the Sun ejected the largest plasma cloud since the beginning of the year. The emission was from the side opposite to the Earth, and therefore did not pose a threat to the planet.

Solar activity can also lead to magnetic storms on Earth. The last time this phenomenon was recorded was on March 4. Its effect lasted for two days.

#4  ^ All true, but the output is irregular and mediated by internal structures - those structures may also be affected as well as plate geometry... assuming there's any relationship to the sun at all...

#3  Your assumption is well taken Mercutio but not evidenced by Kilauea. Kilauea sits on top of a "hot spot" in the middle of the pacific plate. Yellowstone is over a hot spot in the middle of the North American plate.

Plate boundaries shifting evidenced by the ring of fire show earthquakes and volcanics are linked. Mt Fugi would be an example of subduction of one plate under another. The submerged plate heats up as it sinks, Density of the material is lessened as the blob expands and magma works its way to the surface in a usually spectacular way.

#2  If it does actually influence earthquakes, might it also not influence volcanic eruptions, both of which tend to be related to shifts in geologic structures, c.f. Kilauea.
