... 2004 July 26 . A Large Active Region Crosses the Sun . ... Explanation: An unexpectedly large sunspot region is now crossing the Sun. The active region is home to rivers of hot plasma , explosive flares , strong magnetic fields , a powerful Coronal Mass Ejection (CME), and a sunspot group so large it can be seen by the protected eye without magnification. In fact, this region appears larger than Venus did when it crossed the Sun last month. ... About APOD | ...
