nasa Our Solar Dynamics Observatory watched an active region on the Sun — an area with intense, complex magnetic activity — rotate into view on April 18-19, seen here in extreme ultraviolet. These bright, towering arches consist of charged particles spiraling along magnetic field lines that were revealed in this view in a wavelength of extreme ultraviolet light. They rise up above the Sun's surface many times the size of Earth. This view covers just 16 hours of activity and our scientists are keeping their eyes on this region to see if it has the potential to produce solar storms. Video Credit: NASA/SDO

Videos of the sun from the Solar Dynamics Observatory are some of my favorite types of science art.

“Space Weather’ can be an issue for spacecraft as electrical discharges from the sun can cause electronic issues for spacecraft. They can also be measured by spacecraft, allowing us to see how the electronic environment of our solar system changes as the sun spits out various pulses of solar wind and Coronal Mass Ejections. This simulation shows how those pulses evolve as they move out towards the outer solar system, Pluto, and the New Horizons spacecraft. And it’s just ridiculously hypnotic.

The sky ablaze

Over the past several days, an active region on the sun fired out several coronal mass ejections in Earth’s direction. The charged particles from those CMEs arrived in the Earth’s area in the evening/early morning on Monday June 22 into Tuesday June 23. The combination of their charges, direction, and intensity produced a geomagnetic storm – surges of electricity and charged particles within the atmosphere that gave rise to impressive auroras across the planet.

Photos came in from all around the world and this is a sampling of the ones that have been freely shared online. These come from Manitoba in Canada, Washington State, and as far south as Kansas.
