Coronal mass ejection News

CME hits Earth — massive geomagnetic storm shows in bright lights

Two nights of spectacular aurora borealis — the result of a massive coronal mass ejection that made a direct hit on Earth's magnetosphere, supercharging our magnetic shield — trumpeted the occurrence of a fierce geomagnetic storm.

Solar event gives prospect of spectacular auroras this weekend

Early yesterday morning NASA released details of an observed solar phenomenon, an Earth-directed coronal mass ejection with the potential to disrupt satellites and communications over the next one to three days.

Sunspot AR1429 erupts with X5.4 flare that may hit Earth

The Sun erupted late on Tuesday (March 6) with the most powerful flares in more than five years. Experts say the flare may interrupt satellites in orbit and disrupt power grids when it reaches Earth.

Solar storm can strip a planet of its atmosphere, says NASA study

A NASA study says that solar storms and Coronal Mass Ejections (CMEs) can erode the surface of a body and also strip it of its atmosphere. The study says CMEs might have caused loss of atmosphere by some planets unprotected by magnetic field.

Sunspot 1302 unleashed towards Earth, detected on shortwave radio

Greenbelt - Scientists are monitoring a sunspot that produced an X1.9-category solar storm that was unleashed over the weekend and could be headed towards Earth. Sunspot 1302 is so strong that it has been detected shortwave radio on this planet.

A coronal mass ejection hit Earth's magnetic field on Oct. 8, 2012 sparking a dramatic display of Northern Lights which subsided 3 days later. The Aurora appears to be casting rays of green sunlight through the clouds. Hugo Løhre photographed the auroras over Lekangsund, Norway, on Oct. 10, 2012.

In the image, you can see that there are two coronal mass ejections (CMEs) projected to influence the Earth's magnetosphere in the next few days. The first is associated with the R1 (Minor) flare observed on 09 Sep while the second is related to yesterday's R3 (Strong) flare.
