THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT
NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov/NOAAscales
Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
Induced Currents – Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
Spacecraft – Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
Radio – HF (high frequency) radio propagation can fade at higher latitudes.
Aurora – Aurora may be seen as low as New York to Wisconsin to Washington state.
Previous Warning
Issue Time: 2013 Mar 15 1220 UTC
A coronal mass ejection (CME) hit Earth’s magnetic field on March 15th at approximately 0500 UT. The impact was not strong but could induce a geomagnetic storm. Aurora watches should be on the alert for good viewing March 15/16.
ALERT: Type IV Radio Emission
Begin Time: 2013 Mar 15 0620 UTC
Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.

It amazing. The univers always excite me with all that mistery elements sun flares and corals it's amazing how ALLAH put every little thing in place. With all of the technology@knowledge out there we only know what we see. Otherwise everything out there is a blackhole. What keep life on earth lies all up in our space. Will we find the answer its up to our wonderfull scientists NASA and the people who always wane no more.my daughter wane be a scientist. She's in grade 1. I will always ancourge her.
