Earth was struck by a powerful Coronal Mass Ejection (CME), with the speed of upwards of 1000 km/sec late on Saturday

Over the next two nights, a widespread display of the northern lights will dance across parts of the U.S., including.

Auroras may be visible from Alaska to Connecticut as speedy solar winds and an incoming CME fuel geomagnetic storm conditions.

The aurora's are back! And may be visible throughout the weekend.

It measures the fluctuations in the Earth's magnetic field, tied to specific geographic locations.

The Northern Lights cannot be seen during daylight hours. Instead, nature’s light show is best seen between the hours of 10 p.m. and 2 a.m. You should also head to a high, north-facing vantage point to be able to spot them, and try to get as far away as possible from any sources of artificial light.

A powerful solar flare erupted early Tuesday, disrupting radio signals across Earth, said the NOAA Space Weather Prediction Center.

The outbursts this week may be signaling that the sun is ramping up its activity. Wednesday’s solar storm peaked around 4:25 a.m. ET, when the sun fired off a huge X-class flare, hurling streams ...
