Last week, new Solar flares and Corona Mass Ejections (CME) were detected by NASA Solar Dynamics Laboratory in which three (3) flares accompanied by CMEs were seen.  

The First CME was detected on August 2, and arrived on Earth on August 4, while the 2nd and third CMEs combined, and arrived on August 5 with the 3rd  CME  given an M9.3 on a scale of 1-9, and predicted to be of a "K-7 storm" in a 1 to 9 scale and is expected to cause aurora displays in countries located at the Mid and High Latitude areas of the Earth.
