The strongest geomagnetic storm of the current solar cycle (Solar Cycle 24) reached G4 Severe levels (Kp=8) on March 17, 2015 and sparked spectacular auroras in both hemispheres of our planet. The event was identified as the combined effects of CMEs which erupted on Mar
A sequence of events led to an Earth-directed asymmetric halo CME on March 15, 2015. The events began with a 14 degree long filament eruption, centered near S24W38, lifting off between 00:45 to 02:00 UTC. This was followed by C2.4 flare at 00:41 UTC and a long duration
Region 2297 rotated onto the SE limb on March 5, 2015 and by March 15 it managed to produce a total of 99 C-flares, 24 M-flares and 1 X-flare. From March 8 to 12, it was the only numbered sunspot region on the solar disk and from the end of March 5 to March 16, with jus
A major solar flare measuring X2.1 (R3-Strong radio blackout) erupted from Region 2297 at 16:22 UTC on March 11, 2015. The event started at 16:11 and ended at 16:29 UTC.A Type II (estimated velocity 1 461 km/s) and IV radio emissions were associated with the event. Type
Region 2297, currently the only numbered sunspot region on the Earth side of the Sun, is crackling with solar flares for the fifth day in a row. After 3 low level M-class flares on March 5 and 6, a long duration M9.2 on March 7 and impulsive M4.5 at 14:33 UTC on March 9
An impulsive solar flare measuring M4.5 at its peak time erupted from Region 2297 at 14:33 on March 9, 2015. The event started at 14:22 and ended at 14:37 UTC.There were no radio signatures that would suggest a Coronal Mass Ejection was produced.This region is rotating
Strong and long duration solar flare measuring M9.2 (R2 – Moderate) at its peak time erupted from Region 2297 at 22:22 UTC on March 7, 2015. The event started at 21:59 and ended at 22:49 UTC.A Type II (estimated velocity 704 km/s) and Type IV radio sweeps were associate
Unnumbered region just rotating onto the southeastern limb produced 3 M-class (R1-Minor radio blackout) and several C-class solar flares in last 24 hours. The largest was a M3.0 that peaked at 04:57 UTC today, with the two M1 flares reaching their peaks at 18:11 UTC (M1
Active region located just beyond the East limb produced a long duration M1.2 solar flare peaking at 18:11 UTC today. The event started 17:06 and ended at 18:26 UTC.This region produced two low level C-class flares before the M1.2 today. It will become fully visible fro
An impulsive solar flare measuring M8.2 (R2 – Moderate Radio blackout) at its peak time erupted from Region 2290 at 01:35 UTC on March 3, 2015. The event started at 01:25 and ended at 01:42 UTC.A Type II (estimated velocity 750 km/s) and IV radio emissions were as
