Satellite Observes Large Solar Eruption

  • The Solar Ultraviolet Imager (SUVI) instrument aboard the Geostationary Operational Environmental Satellites (GOES) West satellite observed a flurry of solar activity in mid-December 2023. This December 11 image from the SUVI 304A channel corresponds to plasma in the upper chromosphere of the Sun at a temperature of about 6,000 kelvins.

Image of the Sun from the Student Helioviewer interface showing active regions labeled with NOAA numbers. The Sun appears in yellow ultraviolet light with swirling magnetic loops, and an Earth scale icon for size comparison is shown in the corner. A data panel at the top displays date, time, and observation settings.

Helioviewer Student Version

The student version of Helioviewer allows learners to access authentic satellite data on solar features and events, including sunspots, flares, and active regions on the Sun’s surface; holes in the corona; eruptions, such as filaments and coronal mass ejections; and the Sun’s magnetic activity.

In a visualization, Earth is shown against the blackness of space. White lines emanate out from the poles showing the planet’s magnetic field lines. Concentric rainbow-colored semicircles on either side of Earth visualize belts of trapped electrons. The second belt from Earth is colored purple to indicate it’s composed of protons as well as electrons. The third belt from Earth (rainbow color) represents the new electron belt.

What NASA Is Learning from the Biggest Geomagnetic Storm in 20 Years

One year on, NASA scientists are still making huge discoveries about the largest geomagnetic storm to hit Earth in two decades, the Gannon storm. The findings are helping us better understand and prepare for the ways in which the Sun’s activity can affect us.

How Can I see the Northern Lights?

To see the northern lights, timing and location are key. This video offers tips to help you catch the aurora in action.

This collage of solar images from NASA's Solar Dynamics Observatory (SDO) shows how observations of the sun in different wavelengths helps highlight different aspects of the sun's surface and atmosphere. (The collage also includes images from other SDO instruments that display magnetic and Doppler information.)For the 52MB Photoshop file click here.

NASA eClips Guide Lites: Solar Images

In this activity participants will create a picture of the sun that can then be examined with colored filters to simulate how specialized instruments enable scientists to capture images and view different features of the sun.
