Solar phenomena - Wikipedia
WEBSolar phenomena are natural phenomena which occur within the atmosphere of the Sun. They take many forms, including solar wind, radio wave flux, solar flares, coronal mass ejections, [1] coronal heating and sunspots.
The sun's magnetic field is about to flip. Here's what to expect.
WEBJun 14, 2024 · The sun is on the verge of a significant event: a magnetic field reversal. This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity...
Atmospheric Phenomena: Halos, Sundogs and Light Pillars
WEBSundogs, light pillars, and other kinds of halos seen in the sky are atmospheric phenomena that occur when light is reflected or refracted by ice crystals in the atmosphere. A Sun halo seen from Lofoten Islands, Norway. The size, shape, and distance from the Earth’s surface of the ice crystals determine what kind of optical phenomenon people ...
Solar Flares (Radio Blackouts) - Space Weather
WEBSolar flares are large eruptions of electromagnetic radiation from the Sun lasting from minutes to hours. The sudden outburst of electromagnetic energy travels at the speed of light, therefore any effect upon the sunlit side of Earth’s exposed outer atmosphere occurs at the same time the event is observed.

Optical Phenomena | NESDIS
WEBThe optical phenomena our satellites observe are often due to the interaction of light from the Sun on our Earth and Ocean, as well as shadows from the Moon. Solar Eclipse. During a solar eclipse, the moon moves between the sun and the Earth, causing its shadow to move across the planet. Learn more about eclipses. Changing of the Seasons.
NASA Develops Process to Create Very Accurate Eclipse Maps
WEB17 hours ago · wasteigerwald. Sep 19, 2024. Article. New NASA research reveals a process to generate extremely accurate eclipse maps, which plot the predicted path of the Moon’s shadow as it crosses the face of Earth. Traditionally, eclipse calculations assume that all observers are at sea level on Earth and that the Moon is a smooth sphere that is ...
