A coronal mass ejection (CME) produced by the long-duration C2 solar flare on March 10/11, 2022, hit Earth early March 13, sparking G2 – Moderate geomagnetic storming. Disturbed conditions are expected to continue into March 14 and 15. The CME started around 18:00…
A G2 – Moderate geomagnetic storm watch is in effect for February 2, 2022, after a long-duration M1.1 solar flare produced an asymmetric, full-halo coronal mass ejection (CME) at 23:32 UTC on January 29. The CME is expected to reach Earth late February 1 or early…
Coronal mass ejection (CME) produced by M1.6 solar flare at 06:40 UTC on October 9, 2021, reached DSCOVR spacecraft at 01:48 UTC and Earth at 02:30 UTC on October 12, 2021. The impact sparked a G2 – Moderate geomagnetic storm. In 24 hours to 00:30 UTC on October 12,…
A coronal mass ejection (CME) produced by a filament eruption around 10:00 UTC on May 9, 2021, has reached Earth at 06:43 UTC on May 12. G3 – Moderate geomagnetic storm levels were observed at 12:59 UTC. The CME arrived at the DSCOVR spacecraft at 05:47 UTC. Solar…
A geomagnetic sudden impulse — CME produced by a long-duration C7.4 solar flare on December 7, was observed at DSCOVR satellite at the L1 point at 01:32 UTC on December 10. The total field reached 16 nT while wind speeds topped out near 571 km/s, producing a period…
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…
Our Sun launched two solar storms this week, one of which was Earth-directed, Space Weather Physicist Dr. Tamitha Skov reports in her latest space weather forecast released July 14, 2020. The storm has hit, right on time, and all through the night people have been…
Solar wind parameters over the past 24 hours were indicative of enhanced solar wind environment, likely caused by a combination of a glancing blow from a slow-moving Coronal Mass Ejection and influences of a negative polarity CH HSS. Total IMF strength was at 5 to 6…
An asymmetric full halo CME with a likely Earth-directed component erupted May 6, 2019. The source is still unknown, it is possible this was another stealth CME. Sun's northeastern limb continued exhibiting increased CME activity on May 6 and 7, 2019. This…
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…
