News Stories relating to "solar flare"
Tuesday, January 21, 2014
As if we needed any more factors to influence our already unpredictable weather, scientists are now concerned about the lack of activity on the sun, which appears to have diminished significantly.
The periodic changes in the sun's activity, such as changes in levels of solar radiation, coronal mass ejections and solar flares, are...

On Tuesday, the sun's first major solar flare of the year emerged from a massive sunspot on the surface of our favourite star, known as AR1944 and described by NASA as "one of the largest sunspots seen in the last 10 years."

The universe is putting on its own Thanksgiving Day light show in the form of Comet ISON, which is set to graze the sun tomorrow.
Assuming that the comet does not disintegrate under the pressure of strong gravitational forces or solar energy, it is set to be one of the most brilliant comets of this century.

In the early hours of Tuesday, August 20, a comet estimated to be only sixty to a hundred feet across dove into the sun, causing a huge solar explosion.
Just before the comet hit, a coronal mass ejection exploded off the sun's surface. While there is no known reason that there would be a connection between a CME and the impact of a...

In the year 775 AD, the sun didn't just emit a large flare, it emitted something close to a superflare, and scientists who have been studying this mysterious and extremely dangerous phenomenon now believe that they understand what caused it, and the news is disturbing. In 775, auroras appeared in Europe after sunset that were recorded as 'the...

Two weeks ago the sun emitted an electromagnetic pulse that would have caused a catastrophe on Earth had it struck us. But it passed through Earth's orbit two weeks before we arrived at the point of intersection. Had it hit our planet, it would have destroyed hundreds of the massive transformers that our electric grids depend on. It is...

Over the past 48 hours, the sun has exploded with no fewer than four x-class flares. X flares are the most powerful type of flare. Sunspot AR1748 has produced the flares. The latest X-flare from the sunspot occured on May 15th at 0152 UT. For four x-flares to take place over such a...

It's happened before: In 1859, sunspots erupted, causing sparks in telegraph offices that set paper on fire. Today, 150 years later, we are much MORE "wired," and sun...

NASA has warned that a huge solar flare now developing could cause
a dangerous solar storm that could disrupt electrical grids on Earth.
At present NASA is estimating a 15% chance...

The British Royal Academy of Engineering has completed a study of the UK power grid showing that it is relatively well prepared to weather a solar superstorm
--but the opposite is true in the United States.

An X-5 solar flare has sent a coronal mass ejection directly toward earth. The CME is now impacting earth's atmosphere, and has the potential to disrupt satellites, unprotected power grids and global positioning systems. While there may not be a strong effect on well protected satellites and power grids in the developed world, there is a greater...

An 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...
