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.

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.
