- Sunspots: What are they, and why do they occur? | Space
Sunspot positions also change throughout the solar cycle During the solar maximum, many sunspots are found along mid-latitudes (approximately 30 degrees north and 30 degrees south)
- Sunspot regions | Solar activity | SpaceWeatherLive. com
On this page you'll find an overview of all the visible sunspot regions on the Sun together with their properties, images and the chances on solar flares or proton events This page is updated daily and the sunspot images every hour
- Sunspots - Solar and Heliospheric Observatory
NOTICE: There is an image outage of the Sunspot images due to a cooling water line burst in the Joint Science Operations Center (JSOC) at Stanford University on 2024-11-26 The images are provided by the Solar Dynamics Observatory (SDO) mission
- Sunspots - NASA Science
This video, captured by NASA’s Solar Dynamics Observatory between July 5 to 11, 2017, shows a sunspot moving across the Sun Like freckles on the face of the Sun, sunspots appear to be small features, but size is relative: The dark core of this sunspot is actually larger than Earth
- What are Sunspots and What Causes Them? | High Point Scientific
Sunspots often form in groups, with each sunspot usually somewhere between 10,000 and 50,000 miles (16,000 to 80,000 kilometers) in diameter In comparison, the Earth is just under 8,000 miles (13,000 kilometers) in diameter, so the vast majority are larger than the Earth
- Sunspots Solar Cycle - NOAA NWS Space Weather Prediction Center
Sunspots appear in a wide variety of shapes and forms The darkest area of a sunspot (also the first to be observed) is called the umbrae As the sunspot matures (becomes more intense), a less dark, outlying area of well-defined fibril-like structure develops around the umbrae - called penumbra
- Sunspot | Solar Flares, Magnetic Fields Sunspots | Britannica
sunspot, vortex of gas on the surface of the Sun associated with strong local magnetic activity Spots look dark only by contrast with the surrounding photosphere, which is several thousand degrees hotter The dark centre of a spot is called the umbra; the outer, lighter ring is the penumbra
- Sunspots - Center for Science Education
If you could cut an average sunspot out of the Sun and place it elsewhere in the night sky, it would be about as bright as the full Moon Sunspots have a lighter, outer section called the penumbra and a darker, central region named the umbra
