An approximate 10-degree filament eruption, centered near S36E33, was observed in GONG H-alpha imagery beginning at 09:58 UTC on November 24, 2021. An associated coronal mass ejection (CME) was observed in SOHO/LASCO C2 imagery beginning at 14:12 UTC on November 24…
A powerful double solar flare eruption took place beyond the Sun's east limb early October 18, 2017. The responsible region is now rotating into Earth view and will be visible in a couple of days. The eruption was associated with a Type II (estimated velocity 1…
An eruption near the center of Earth-facing side of the Sun produced a partial HALO CME (coronal mass ejection) during the early UTC hours of May 23, 2017. The CME is weak, but it has an Earth-directed component. Arrival at Earth is expected around 12:00 UTC on May…
Scientists discovered what triggers the natural thermostat of our planet's upper atmosphere, responsible for cooling the air previously heated by the intense solar activity. The solar flares and coronal mass ejections (CMEs) can cause damage to satellites…
On July 23, 2012, a massive cloud of solar material erupted off the sun's right side, zooming out into space. It soon passed one of NASA's Solar Terrestrial Relations Observatory, or STEREO, spacecraft, which clocked the CME as traveling between 2 900 – 3…
The Earth's magnetic field got disturbed in response to the arrival of the September 10 halo CME caused by X1.6 solar flare. Magnetometers around the world recorded a Geomagnetic Sudden Impulse at 15:55 UTC which signaled the arrival of the CME at
Solar activity was at low levels during last 24 hours, however, that might change today and in the days ahead. Active Region 2036 exhibited rapid growth over the last few days and is now almost directly facing our planet. Earth directed eruption
A geomagnetic sudden impulse, indicating the arrival of the March 23 CME, was observed at the Hartland magnetometer (23 nT) at 20:09 UTC on March 25.
The geomagnetic field is expected to be at unsettled to active levels (below G1-Minor) early on March 26 as CME
Researchers at the UCL studying details of Coronal Mass Ejections (CMEs) have noticed that those eruptions have a surprising twin in the depths of space: the tendrils of gas in the Crab Nebula, which lie 6500 light-years away and are millions of
Solar activity was at moderate levels in last 24 hours (12:30 UTC). Region 1974 (S13W05, Fsc/beta-gamma-delta) continued to exhibit growth and separation in the intermediate spots, and was responsible for the majority of the flare activity throughout the
