Sunspot AR 4334

Sunspot AR 4334 is a moderate-sized, magnetically complex active region currently visible on the Sun’s surface. It contains 12 visible spots and spans an area of 150 millionths of the solar hemisphere. This region has produced 3 C-class flares so far and currently shows a 65% probability of C-class, 20% of M-class, and 5% of X-class flares. It is located at heliographic latitude S16°, Earth-facing longitude 7°, and Carrington longitude 200°.

Sunspot Evolution

The following graphs show how this sunspot region 4334 has changed over time. The first graph displays its total area on the solar surface, while the second shows the number of individual sunspots observed within the region.

Sunspot Area

This graph illustrates the physical growth of the sunspot region, measured in millionths of the solar hemisphere (MSH). Increases in area typically indicate developing magnetic complexity and potential for solar activity.

Spot Count

This graph shows the number of visible sunspots within the region at each observation time. A higher spot count often corresponds with a more active or complex region.
