M9.6 solar flare erupts from Region 2993, CME produced
A strong solar flare measuring M9.6 at its peak erupted…
Major, long-duration X1.0 solar flare erupts from AR 2887, Earth-directed CME produced
A major, long-duration solar flare measuring X1.0 at its peak erupted from geoeffective Active Region 2887 at 15:35 UTC on October 28, 2021. The event started at 15:17 and ended at 15:48 UTC. The event was associated with a Type II Radio Emission with an estimated…
Glancing-blow expected after weak B1.2 solar flare
A weak solar flare measuring B1.2 at its peak erupted on August 16, 2020, producing a coronal mass ejection (CME). Consensus model results suggest an arriving glancing blow on August 20 — producing unsettled to active geomagnetic field conditions, with a chance for…
C1.3 solar flare erupts from geoeffective Region 2734, CME impact expected March 11
A long-duration solar flare measuring C1.3 at its peak erupted from Region 2734 (Alpha) at 03:19 UTC on March 8, 2019. The event started at 03:07, peaked at 03:19 and ended at 03:58 UTC. This event was associated with a Type II Radio Emission registered at 03:15 UTC…
C5.0 solar flare erupts from AR2733, the strongest since February 18, 2018
A weak solar flare measuring C5.0 at its peak erupted from Active Region 2733 at 13:22 UTC on January 26, 2019. The eruption started at 13:12 and ended at 13:34 UTC. This was the strongest solar flare since February 18, 2018. It was preceded by B1.5 at 03:49 UTC,…
How solar flares accelerate charged particles into super high speeds
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)…
Moderately strong M5.1 solar flare erupted
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
New emerging sunspots raise chances of flares in the coming days
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
Third major X-class solar flare in 24 hours – X3.2 on May 14, 2013
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
Intro to space weather vocabulary – video
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.
