• Impulsive M1.3 solar flare erupts from big Region 2665

    Big sunspot region 2665 (beta) erupted with an impulsive solar flare measuring M1.3 at its peak time on July 9, 2017. The event started at 03:09, peaked at 03:18 and ended at 03:37 UTC. The last time our star unleashed an M-class solar flare was on July 4, 2017….

  • Impulsive M1.3 solar flare erupts near the west limb

    Solar activity was at moderate levels on July 3, 2017, with 14 B-class and one impulsive M1.3 solar flare observed at 16:15 UTC. The M-class event started at 15:37 and ended at 16:18 UTC. The last time our star unleashed an M-class solar flare was on April 3, 2017….

  • Partial-halo CME impact sparks G1 geomagnetic storm

    A partial-halo coronal mass ejection (CME) produced on June 28, 2017 hit Earth's magnetic field at 17:12 UTC on July 1, almost 24 hours earlier than expected. The impact was weak but managed to spark a G1 – Minor geomagnetic storm 17 hours later. G1 Watch…

  • Filament eruption, glancing blow possible on April 15

    An approximate 14 degree solar filament eruption began at 20:25 UTC on April 9, 2017, from the northeast quadrant of the Sun. The event generated a coronal mass ejection (CME) and a glancing blow is possible on April 15. The CME was first observed in SOHO/LASCO C2…

  • Moderately strong M5.8 solar flare erupts from Region 2644

    A moderately strong solar flare measuring M5.8 (R2 – Moderate) erupted from Region 2644 at 14:29 UTC on April 3, 2017. The event started at 14:19 and ended at 14:34 UTC. This is the 7th and the strongest M-class solar flare since late April 1, 2017. It is also the…

  • Seven M-class solar flares erupt from Region 2644

    Departing Active Region 2644 erupted with seven M-class solar flares since late April 1, 2017. The series started with M4.4 on April 1 and was followed by M5.3, M2.3, M2.1 and M5.7 on April 2, and M1.2 and M5.8 on April 3. Multiple coronal mass ejections were…

  • Impulsive M1.0 solar flare erupts from Region 2615

    An impulsive, moderately strong solar flare measuring M1.0 at its peak erupted at 17:26 UTC on November 29, 2016. The event started at 17:19 and ended at 17:26 UTC. This is the first M-class solar flare since M1.3 on August 7, 2016. With the approach of solar…

  • Spotless Sun heralds Solar Minimum after CME producing Region 2567 departs

    After Active Region 2567, the source of 7 M-class and numerous C-class solar flares between July 21 and 24, rotated away from the visible disk, our Earth facing Sun is again spotless. This is the third 'spotless Sun' since June 3, and although it is a…

  • 3 strong M-class solar flares erupt from Region 2567, CME produced

    Three strong solar flares erupted from Active Region 2567 early on July 23, 2016 – M5.0, M7.6, and M5.5. A Coronal Mass Ejection (CME) was produced during the third one, however, this region is not in a position to produce Earth-directed CMEs. The first flare…
