3-8-12 Solar Storm Update

Hey Space Placers!

Please read yesterday's blog before this one for background.

The X5 (Extreme Class) event from Sunspot Group 1429 was so powerful that the Sun experienced a "tsunami" shock wave that is plainly visible in the video here:

The true effect on the Earth has yet to be determined but there is the possibility of a G3 (strong) geomagnetic storm:
Power systems: voltage corrections may be required, false alarms triggered on some protection devices.
Spacecraft operations: surface charging may occur on satellite components, drag may increase on low-Earth-orbit satellites, and corrections may be needed for orientation problems.
Other systems: intermittent satellite navigation and low-frequency radio navigation problems may occur, HF radio may be intermittent, and aurora has been seen as low as Illinois and Oregon (typically 50° geomagnetic lat.)**.

Sunspot Group 1429 may still produce additional solar flares and is now almost pointed directly at Earth:

More to come as the Sun is just beginning solar maximum!
