According to the , quoted by Space, this eruption peaked at 10:00 am GMT yesterday from sunspot AR274. The mentioned sunspot has been very active in recent days. The blast caused an R3 blackout of radio waves in Africa and Europe, disrupting high-frequency radio communications on the sunlit side of the Earth.
The explosion is the latest in a series of solar flares from spot AR4274, which emitted X1.7 flares on November 9th and X1.2 flares on November 10th. According to the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Forecast Center, the flares were associated with coronal mass ejections (CMEs) that may merge and reach Earth tonight. This phenomenon can cause severe geomagnetic storms (at G3 level) and create widespread auroras.
The solar mass launched yesterday is heading towards Earth at a speed of about 4.4 million miles per hour and is likely to join the cluster. NOAA predicts that this CME may make landfall around noon on November 12. With the addition of a CME in addition to the previous two examples, it is possible that Earth will experience a severe G4-level geomagnetic storm.
In terms of power, solar flares are classified into five categories: A, B, C, M, and X, each stage representing a 10-fold increase in energy and efficiency. X solar flares are the most powerful category.
