This page provides a prediction of the aurora’s visibility tonight and tomorrow night in the charts below. The animations further down show what the aurora’s been up to over the last 24 hours and estimates what the next 30 minutes will be like.

Though many geomagnetic storms are associated with clouds of solar material that explode from the sun in an event called a coronal mass ejection, or CME, this storm was caused by an especially fast stream of solar wind.

What Causes the Aurora? The aurora is formed from interactions between the solar wind streaming out from the sun and Earth’s protective magnetic field, or magnetosphere. The aurora is one manifestation of geomagnetic activity or geomagnetic storms.

3 天之前 · Aurora is the Latin word for “dawn” and is also the name of the Roman goddess of the dawn. Europeans living far from the Arctic Circle usually experienced auroras as a faint red glow to the north, resembling the reddish glow in the east at dawn. ... When the solar wind buffets the magnetosphere under these conditions, the field lines of the ...

The satellite samples and measures the solar wind 15 to 60 minutes before it reaches Earth, and the SWPC uses this data to issue warnings. Note: Since July of 2016, DSCOVR is the primary source of solar wind data.

2025年1月3日 · Aurora alert — a coronal hole is spewing fast solar wind toward Earth, potentially boosting geomagnetic activity and supercharging northern lights Jan. 4 to Jan. 5.

Our Sun generates a strong solar wind, which carries about one million tons of extremely hot plasma (electrons, protons, and other particles) away from the Sun every second. Earth’s magnetosphere acts like a shield that protects us from most of …

When space weather activity increases and more frequent and larger storms and substorms occur, the aurora extends equatorward. During large events, the aurora can be observed as far south as the US, Europe, and Asia. During very large events, the aurora can be observed even farther from the poles.

2025年1月21日 · An aurora is a glowing light show in the Earth's upper atmosphere, occurring at altitudes between about 85 and 600 km. ... The particles travel on the streaming solar wind or as bursts during coronal mass ejections, which are often linked with solar flares. As the solar wind travels through space, it interacts with the magnetosphere and ...
