solar flare The solar flare observed on June 7 is expected to cause some disruption in power grids, satellites and other devices. Historically, major solar storms have had massive effects on earth, affecting various technologies, and captivated the general public. Here are the top 10 among such events in history.The CME, travelling faster at 1,400 km/s, should deliver a glancing blow to Earth's magnetic field during the late hours of Wednesday or Thursday, which could disturb Earth's power grids and global positioning systems that heavily rely on satellite communications.
The National Oceanic and Atmospheric Administration's (NOAA) space weather prediction center expects the flare to cause G1 (minor) to G2 (moderate) levels of geomagnetic storm activity Wednesday, beginning around 1800 UTC (1 pm EST) with the passage of a fast CME. But the center revised its prediction for Geomagnetic Storm activity, now expecting the CME to pass Earth around 1200 UTC (7 pm EST) on June 9. The center said a prompt Solar Radiation Storm reached the S1 (minor) level soon after the impulsive R1 (minor) Radio Blackout at 0641 UTC. The Solar Radiation Storm includes a significant contribution of high energy (>100 MeV) protons, the first such occurrence of an event of that type since December 2006. But the center revised its prediction, and now expects primarily G1 (minor) NOAA Scale levels, and for the storm to persist for 24 hours. The intensity of the Solar Radiation Storm is expected to be "little" affected by the passage of the CME-driven shock.
