Solar Flare Heads Earthward 03.07.12  


Hunker Down for a bit...


Update: A coronal mass ejection (CME) hit Earth's magnetic field on March 8th around 1100 UT. The impact was weaker than expected, sparking only a mild (Kp=5) geomagnetic storm. However, the storm could intensify in the hours ahead depending on electromagnetic conditions in the wake of the CME.


Be cautious, alert to odd things happening. If anything goes weird, unplug all electronic devices and wait for the solar storm to pass. Things will probably be OK.

This movie of the March 6, 2012 X5.4 flare was captured by the Solar Dynamics Observatory (SDO) in the 171 Angstrom wavelength. One of the most dramatic features is the way the entire surface of the sun seems to ripple with the force of the eruption. This movement comes from something called EIT waves – because they were first discovered with the Extreme ultraviolet Imaging Telescope (EIT) on the Solar Heliospheric Observatory. Since SDO captures images every 12 seconds, it has been able to map the full evolution of these waves and confirm that they can travel across the full breadth of the sun. The waves move at over a million miles per hour, zipping from one side of the sun to the other in about an hour. The movie shows two distinct waves. The first seems to spread in all directions; the second is narrower, moving toward the southeast. Such waves are associated with, and perhaps trigger, fast coronal mass ejections, so it is likely that each one is connected to one of the two CMEs that erupted on March 6. Source: NASA/SDO/AIA

Historical Precedence

It has happened before, but we are more vulnerable now. Telegraph offices burned in 1859. What can it do tour sensitive electronics today?

"Electric wires in telegraphs suffered from induction effects during the extreme magnetic storm. Rubenson(1882) describes a geomagnetically induced damage,which occurred during the extreme magnetic storm of 1859 in Gothenburg (Geomagn. Lat. 56N), Sweden:

During September 2nd and 3rd atmospheric electricity was so high that the telegraphic connections were broken down for many hours at several occasions. In the City Telegraphic Office it was observed that the galvanometer needle of the telegraph apparatus was sometimes motionless, sometimes it moved restlessly. The telegraphist, who on the morning of September 2nd was disconnecting the earth, got a strong electric shock when touching the cable. On the evenings of September2nd and 3rd the sky was full of majestic northern lights.On the following evenings they were seen again and the galvanometer behaved similarly but less disturbed. Due to high atmospheric electricity it was impossible to send telegrams for about 24 hours."
