  • Sunspot - Wikipedia
    Sunspots are temporary spots on the Sun's surface that are darker than the surrounding area They are one of the most recognizable Solar phenomena and despite the fact that they are mostly visible in the solar photosphere they usually affect the entire solar atmosphere
  • 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 Magn Class Magn
  • Sunspots and Solar Flares - NASA Space Place
    What are sunspots and solar flares? Sunspots are areas that appear dark on the surface of the Sun They appear dark because they are cooler than other parts of the Sun’s surface Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots
  • Sunspots: What are they, and why do they occur? | Space
    Sunspots are dark, planet-size regions of strong magnetic fields on the surface of the sun They can spawn eruptive disturbances such as solar flares and coronal mass ejections (CMEs)
  • 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 Status updates are provided at SDO's JSOC Emergency Resources page
  • Sunspots - NASA Science

  • The Sun and Sunspots - National Weather Service
    Sunspots are areas where the magnetic field is about 2,500 times stronger than Earth's, much higher than anywhere else on the Sun Because of the strong magnetic field, the magnetic pressure increases while the surrounding atmospheric pressure decreases
  • What are Sunspots and What Causes Them? - High Point Scientific
    At some time or another, you’ve probably seen photos of the Sun with dark spots on its surface These markings, known as sunspots, have been studied for hundreds of years, but what are they? What causes them? And is there a way to safely see them for yourself?
  • Sunspots - Center for Science Education
    Sunspots are dark, planet-sized regions that appear on the surface of the Sun They are caused by twisting, chaotic magnetic fields from within the Sun’s convective zone These powerful magnetic disturbances produce active regions on the Sun, which can often create solar flares and coronal mass ejections (CMEs)
