NASA has warned that a huge solar flare now developing could causeAn X-Class solar flare erupted today from a sunspot that has grown remarkably fast from a small active region to a much larger one. Yesterday, the spot was barely visible. Now it is seven times the diameter of the earth. At present sunspot 484 is near the sun's northeastern limb and is not pointed directly toward earth. However, this active...
NOAA has issued a space weather advisory in response to an X-1 class solar flare that took place at 8:20AM PST. A G2 class magnetic storm is expected to reach earth around 6:00PM PST on Monday. A magnetic storm of this magnitude has the capacity to cause can lead to minor problems with electrical power systems, spacecraft operations,...
The most powerful solar flare since April has unexpectedly erupted, causing radio blackouts across the sunlit side of the earth at this time. Sunspot group AR9591 unleashed the flare at 12:45PM Eastern Daylight Time today. The explosion also sent a brilliant coronal mass ejection into space. However, the CME is not heading directly toward earth...
Between 9 and 10 AM on Wedneday, April 11, a severe geomagnetic storm struck earth. Auroras may be visible into the middle lattitudes tonight, which would include most if not all of the United States.
A G-4 level magnetic storm is the second highest on the scale. It is capable of causing widespread voltage control problems in power...
A powerful X-class solar flare erupte at 1:25 AM EDT Tuesday, causing radio blackouts across the eastern hemisphere of earth and triggering a minor radiation storm. The flare hurled a coronal mass ejection directly toward earth. This CME joins another, smaller one already heading for our planet. The CMEs will reach earth on Wedneday or Thursday...
At 1015 Universal Time, an X-class solar flare was emitted from the sunspot region 9393, sending a coronal mass ejection toward earth. This follows a coronal mass ejection emitted two days ago. Energy from the first CME is expected to arrive on Friday, and from the second on Saturday.
With an X-class flare, which is the most powerful...
An unusually high number of sunspots are now crossing the solar disk as it rotates. One of these, Sunspot 9393, is a very large formation, and could result in an X-class flare, the most powerful measured.
A sunspot this large has not been observed in many years, and it presents a very dramatic image on the face of the sun. The spot is...
