Active Sunspots

Below is a list of all sunspot regions currently visible on the solar disk. Each sunspot is an area of intense magnetic activity, often associated with solar flares and coronal mass ejections.

Every entry includes the NOAA active region number, magnetic classification, estimated area in millionths of the solar hemisphere (MSH), number of distinct spots, and flare probabilities. The list is continuously updated with the latest data from solar observatories.
