Strong solar activities have long been known to cause damages to electrical grids and global communication systems. However, there exist evidence that solar activities have strong correlation with abrupt weather conditions and tectonic activities, including storm…
In the giant system that connects Earth to the sun, one key event happens over and over: solar material streams toward Earth and the giant magnetic bubble around Earth, the magnetosphere helps keep it at bay. The parameters, however, change: The particles streaming in
Heliophysics scientists study energy transformation from one event to the other and which electromagnetic waves create which conditions near Earth. Space weather effects can disrupt satellites in space, so scientists need to understand the system in even more detail.
“Understanding interaction between the Earth’s magnetic field, or magnetosphere, and its upper atmosphere – known as the thermosphere/ionosphere – is especially important this year and in 2014, said Yue Deng, an assistant physics professor at University of Texas.
We are now fully into solar maximum and the United Nations is taking steps to organize an international response to space weather effects. Space weather was added to the regular agenda of the COPUOS Science and Technical Subcommittee, which means the UN is recognizing
Solar activity ranged from low to high levels in last 7 days. Activity was low during October 15 – 19 due to mostly low-level C-class flares. The largest flare of this interval was a C7 on October 17, 2012 at 08:02 UTC from Region 1596 (N07, L=150, class/area
Solar activity ranged from very low to moderate levels. Region 1476 (N09, L=180, class/area Fkc/1050 on 09 May) continued to be the major contributor of x-ray flare activity throughout the week. It produced 13 C-class flares and an M-flare.Region 1476 began the
The northern lights interfere with radio communications, GPS navigation and satellite communications. Researchers are now going to launch 20 satellites containing world class instruments from the University of Oslo to find out why.Satellites are becoming increasingly
Recent research shows that the space age has coincided with a period of unusually high solar activity, called a grand maximum. Isotopes in ice sheets and tree rings tell us that this grand solar maximum is one of 24 during the last 9300 years and suggest the high
NOAA/SWPC have determined that the CME from Active Region 1402 near disk center from the latest M3 solar flare will likely pass above (north) of Earth. This glancing blow will cause just G1 (Minor) Geomagnetic Storm activity. We can expect first signs starting from
