Observation Settings

Or select it on the map:
This Earth map fragment is intended to illustrate celestial motion across the sky, emphasizing both bearing and elevational perspectives. The map's center point corresponds to the transit, showcasing celestial objects at their highest point, while elevation gradually decreases towards the map edges. This dynamic representation offers insights into the changing positions of celestial bodies with a focus on their bearing and elevational trajectories.

Real-Time Interactive Sun Map

Double-click to unlock the map
Selected map type: HMI Intensitygram

Explore the Sun in real time using our interactive map, which displays the solar disk across multiple wavelengths — including visible light, ultraviolet, and magnetograms. Track active sunspot regions visually as they evolve on the surface of the Sun.

The map allows you to switch between different spectral views to observe magnetic activity, coronal structure, and sunspot positions in detail.

Below the map, you'll find a live list of all currently visible sunspots. Each entry includes the NOAA sunspot number, magnetic classification, flare risk, and physical properties such as area and spot count.

  • Interactive Solar Map: View the Sun in different wavelengths and follow active regions in real time
  • Detailed Sunspot List: Includes magnetic class, size (MSH), flare probabilities, and more

Both the map and the list are updated continuously using the latest observations from solar observatories.

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.
