Moderately strong M7.1 solar flare erupts from AR 3288
A moderately strong solar flare measuring M7.1 erupted at 13:09 UTC on May 1, 2023. The event started at 13:02 and ended at 13:09 UTC.
Solar storm briefing and highly informative Q&A by Dr. Tamitha Skov
This highly informative solar storm briefing and Q&A session was made by Dr. Tamitha Skov also known as Space Weather Woman. One of the most interesting parts of the video is when she discusses red aurora, Earth’s weakening magnetic field, the South Atlantic Anomaly, and the upcoming Earth’s magnetic pole flip.
A week of intense solar activity: 2 X- and 25 M-class flares, with 2 Earth-directed CMEs
The period of January 9 to 15, 2023, was marked by intense solar activity, with numerous M and X-class flares being observed. The largest event of the period was an X1.9 flare on January 9, followed by an X1.0 on January 10. There were a total of 2 X-flares and 25 M-flares during the period but only two Earth-directed CMEs were observed from this flurry of activity.
Increased solar activity – glancing blow possible on January 19
Solar activity reached high levels in the past 24 hours, with the strongest event being an M6.0 flare from Region 3191. This event was accompanied by a Type II radio sweep and a Coronal Mass Ejection (CME) signature, however, analysis and modeling indicate that no Earth-directed component was produced. A CME was also observed off the southwest limb at 22:00 UTC on January 14, with analysis and modeling suggesting the possibility of a glancing blow on January 19.

40 SpaceX Starlink satellites lost after geomagnetic storm hits Earth
A geomagnetic storm affecting Earth on Friday, February 4, 2022, significantly impacted 40 of 49 SpaceX Starlink satellites launched to low Earth orbit from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida on February 3. Preliminary analysis shows up…
Cosmic rays decreasing as Solar Cycle 25 gains strength
New data provided by the students of Earth to Sky Calculus and Dr. Tony Phillips of SpaceWeather.com show that cosmic radiation levels in the Earth's atmosphere are decreasing as the new solar cycle — Solar Cycle 25 — gains strength. The plot below shows…
Solar filament eruption, possible glancing blow on November 29
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…
Remarkable pink aurora outburst over Norway
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…
Game changer for space weather forecasting: Regional geomagnetic products debut
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…
