| Summary: Most of the auroras pictured below were triggered by solar wind streams flowing from coronal holes. An exception is the widespread display of August 18th, which began when the interplanetary magnetic field (IMF) near Earth turned sharply south (-30 nT) and remained south for many hours. South-pointing IMFs encourage geomagnetic activity. In this case a severe (G4-class) storm developed. See also the July 2003 aurora gallery. Unless otherwise stated, all images are copyrighted by the photographers. |
