This photo was taken during a geomagnetic storm that was most likely caused by a coronal mass ejection from the sun on may 24 , 2010 .
照片拍摄于一次磁暴中,那次磁暴很可能是由2010年5月24日太阳上的日冕物质喷射造成的。
And while aurorae are normally visible only at high latitudes , they can light up the sky even at lower latitudes during a geomagnetic storm .
虽然极光通常只出现在高纬度地区,但是在磁暴发生时,极光也能点亮稍低纬度地区的天空。
Another theory proposed by the 2012 phenomenon is that there will be a geomagnetic reversal on december 21 , 2012 , which could cause a severe disruption in technology .
This could result in stronger geomagnetic storms than we have seen in many years .
这可能会引起更大的磁暴比我们看到的很多年。
Denver-the most powerful geomagnetic storm possible walloped the earth early wednesday , knocking out some airline communications but apparently causing no large power outages or other major problems .
They 'd all need to be hardier and thicker-skinned than current humans , in order to deal with the greater influx of cosmic radiation they would experience in the absence of a geomagnetic field .
Big cmes that hit earth squarely can wreak havoc , spawning powerful geomagnetic storms with the potential to disrupt gps signals , radio communications and power grids .
