Sunspot AR 4274

Sunspot AR 4274 is a large, magnetically complex active region currently visible on the Sun’s surface. It contains 19 visible spots and spans an area of 330 millionths of the solar hemisphere. This region has produced 2 C-class flares, 7 M-class flares, 1 X-class flare so far and currently shows a 99% probability of C-class, 70% of M-class, and 25% of X-class flares. It is located at heliographic latitude N24°, Earth-facing longitude 40°, and Carrington longitude 277°.

Sunspot Evolution

The following graphs show how this sunspot region 4274 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

Area 0 364

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

Sunspots 0 21

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.
