Lights Over Lapland photographer Chad Blakley captured this amazing view of the aurora borealis in Sweden on January 24th, 2012. The January 23rd solar flare and ensuing coronal mass ejection are the 'lighting engineers' of this incredible display. Credit: Chad Blakley http://www.lightsoverlapland.com
Um apagão global poderia levar meses a resolver e teria o potencial para causar centenas de milhares de milhões de euros em prejuízos, talvez milhares de mortos.
This eruption hurled a bright CME into space. First-look data from STEREO-B are not sufficient to determine if the cloud is heading for Earth. Our best guess is "probably, yes, but not directly toward Earth." A glancing blow to our planet's magnetosphere is possible on March 8th or 9th.

Another CME, part of the recent R3 (Strong) Radio Blackout event at 0024 UTC March 7 (7:24 p.m. EST March 6) is forecast to pass ACE early morning UTC on March 8 (start of day EST March 8) . Geomagnetic storm periods reaching the G3 (Strong) level are likely from that CME. Finally, a Solar Radiation Storm is also in progress and levels are currently above the S3 (Strong) threshold. Region 1429 remains potent and subsequent activity is certainly possible. Updates here as conditions warrant.
__________________The coronal mass ejection (CME) associated with the R3 (Strong) Radio Blackout event from 0024 UTC March 7 (7:24 p.m. EST March 6) arrived at ACE at 1045 UTC today (5:45 a.m. EST March 8). So far the orientation of the magnetic field has been opposite of what is needed to cause the strongest storming. As the event progresses, that field will continue to change. Based on overall strength, the predictions for periods reaching the G3 level look justified. Additionally, the Solar Radiation Storm levels remain above the S3 (Strong) threshold at this time, with values rising momentarily with shock arrival. Region 1429 remains potent and subsequent activity is certainly possible. Updates here as conditions warrant.
