>  of our star. On Nov. 11th and 12th their holographic maps revealed giant
>  sunspots 486 and 488--the same active regions that caused so much 
>  intense
>  space weather a few weeks ago.
>  
>  These spots are still active. Explosions from their vicinity have been
>  hurling clouds of gas over the sun's limb in recent days. The sun's

>  sun. More solar storms are possible when they reappear on or about Nov.
>  19th.

>  Meanwhile, another one of last month's giant sunspots has already
>  reappeared. Active region 484 is peeking over the sun's eastern limb. 
>  The
>  sunspot looks smaller than it did in late October, but it too remains
>  active--hurling a bright coronal mass ejection into space on Nov. 13th.
