A large sunspot is modifying the sun's vibrations.
Sunspots appear as cool patches on the sun's surface
Magnetic fields arise as electrically charged gases whirl within our closest star.
Magnetic fields may be so powerful that they block heat from reaching the surface, generating a sunspot.
Sunspots are a source of solar flares and coronal mass ejections (CMEs) owing to their high magnetic fields.
Flares and CMEs that hit Earth may interrupt radio communications and electricity infrastructures. Space weather causes auroras.
Specially-designed telescopes can see sunspots on the Earth-facing side of the sun. Backside sunspots demand a different method.
Spaceweather.com reported Tuesday morning that two large sunspots are affecting the sun's vibrations.
The two sunspots should be visible in a few days.
