Sunspot Evolution

The following graphs show how this sunspot region 4479 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 0 793

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 38

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.
