Scientists have made another step toward determining how solar flares accelerate charged particles like electrons and protons to speeds of almost the order of light. The new capabilities of the National Science Foundation's Karl G. Jansky Very Large Array (VLA)…
A moderately strong M5.1 solar flared erupted around Sunspots 2172 and 2173 at 02:58 UTC on September 28, 2014. The event was associated with a Type II and Type IV Radio Emissions, along with a 10cm Radio Burst (TenFlare). GOES X-Ray flux and SDO's AIA 094 image
Solar activity is currently at very low levels. However, a group of new sunspots are emerging over the southeastern limb and the chance of flares is increasing with it. This new group is increasing the solar EUV flux absorbed in the Earth’s
Solar activity increased rapidly in the past two days with three M-class and three major X-class solar events. The latest recorded is the strongest flare so far this year, recorded as X3.2 on May 14, 2013 at 01:17 UTC. This event was associated with Type II and
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.
Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in association with changes in magnetic field lines
Sun erupted slow-moving Coronal Mass Ejection (CME) on February 19, 2013. Goddard Space Flight Center reported that the bulk of the plasma cloud was directed to the north of Earth. Still, we can expect a glancing blow around February 22, 2013. Minor to moderate
Solar activity has been at moderate to high levels for the past 24 hours. AR1652 produced two M-class and 8 C-class solar flares in the past 24 hours, and it has rapidly evolved to a compact beta-gamma-delta configuration. This active region erupted M1.0 flare
Sunspot 1654 produced a long duration C8.0 solar flare at 17:46 UTC on January 10, 2013. Besides C8 event, solar activity remained at low levels. There are currently 9 numbered sunspots with 1652 and 1654 as the largest active regions. Region 1652 is classified as a
