| Description |
Huge sunspot group -- Active region 9393 as seen by MDI hosted the largest sunspot group observed so far during the current sol Joseph B. Gurman Normal Joseph B. Gurman 1 0 2001-04-11T18:27:00Z 2001-04-11T18:27:00Z 1 NASA GSGC 1 1 9.2511 800x600 0 0 Huge sunspot group -- Active region 9393 as seen by MDI hosted the largest sunspot group observed so far during the current solar cycle. On 30 March 2001, the sunspot area within the group spanned an area more than 13 times the entire surface of the Earth! It was the source of numerous flares and coronal mass ejections, including the largest flare recorded in 25 years on 2 April 2001. Caused by intense magnetic fields emerging from the interior, a sunspot appears to be dark only when contrasted against the rest of the solar surface, because it is slightly cooler than the unmarked regions. |

| Description |
Blasting CME -- This LASCO C2 image, taken 8 January 2002, shows a widely spreading coronal mass ejection (CME) shooting billi Joseph B. Gurman Normal Joseph B. Gurman 2 1 2003-04-07T18:42:00Z 2003-04-07T18:42:00Z 1 NASA GSGC 1 1 9.2511 800x600 0 0 Sunspot series -- This was the largest sunspot group of this solar cycle as it moved with the Sun's rotation. On 30 March 2001, the sunspot area within the group (called active region 9393) extended across an area more than 13 times the diameter of the Earth It yielded numerous flares and coronal mass ejections, including the largest X-ray flare recorded in 25 years on 2 April 2001, the last image in the series. Caused by intense magnetic fields emerging from the interior, a sunspot appears to be dark only when contrasted against the rest of the solar surface, because it is slightly cooler than the unmarked regions. |
