A solar filament was observed lifting off the Sun's northeastern quadrant beginning at approximately 04:45 UTC on November 25, 2017. An associated weak Coronal Mass Ejection (CME) was observed in SOHO/LASCO C2 and C3 imagery and the analysis shows a potential…
Over the past couple winters, big displays of pink and white auroras have coincided with spotless suns. The sight is often big enough to make observers wonder if there is a connection, SpaceWeather reports. The most recent remarkable outburst of pink auroras was…
This month, for the first time, scientists have started using a new geospace forecast model that can give unique data for each 900 km2 (350 mi2) plot of Earth, up to 45 minutes before a solar storm hits. The model provides short-term guidance of the state of…
For the first time, retired U.S. Air Force officers involved in forecasting and analyzing the extreme space weather event of May 23, 1967, collectively and publicly describe how great solar and geomagnetic storm at the height of the Cold War almost led to a…
Japanese scientists have developed a new and robust simulation code for Coronal Mass Ejection (CME) events based on the realistic description of the mechanisms behind their generation and propagation through space. The method has been successfully validated using…
An important research project, led by the UK's University of Dundee, aims to improve knowledge of Sun's complex magnetic fields using mathematics. The goal is to find out the effects of space weather caused by the Sun and its magnetic structures origins….
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.
