STRONG SOLAR ACTIVITY: For the third day in a row, active sunspot 1261 has unleashed a strong M-class solar flare. The latest blast at 0357 UT on August 4th registered M9.3 on the Richter Scale of Flares, almost crossing the threshold into X-territory (X-flares are the most powerful kind). The number of energetic protons around Earth has jumped nearly 100-fold as a result of this event. Stay tuned for updates.

INCOMING CLOUDS: At least two coronal mass ejections (CMEs) are now en route to Earth, propelled toward us by eruptions in the magnetic canopy of sunspot 1261 on August 2nd and 3rd. Analysts at the GSFC Space Weather Lab have just produced a new 3-D model of the advancing CMEs. Click on the image to set the clouds in motion below:

Incoming Geomagnetic Storm Alert:C7-Flare/CME (June 21st, 2011).

June 21, 2011 Comments off

INCOMING: Magnetic fields above sunspot complex 1236 erupted during the early hours of June 21st, producing a C7-class solar flare and a full-halo CME. The expanding cloud appears to be heading almost directly toward Earth:

This does not appear to be an especially powerful CME. Nevertheless, the incoming cloud could trigger polar geomagnetic storms when it reaches Earth on or about June 23rd. The aurora outlook favors southern hemisphere observers, where solstice skies are winter-dark. Stay tuned for updates.

‘Dramatic’ solar flare could disrupt Earth communications

WASHINGTON – An unusual solar flare observed by a NASA space observatory on Tuesday could cause some disruptions to satellite communications and power on Earth over the next day or so, officials said.

The potent blast from the Sun unleashed a firestorm of radiation on a level not witnessed since 2006, and will likely lead to moderate geomagnetic storm activity by Wednesday, according to the National Weather Service.

“This one was rather dramatic,” said Bill Murtagh, program coordinator at the NWS’s Space Weather Prediction Center, describing the M-2 (medium-sized) solar flare that peaked at 1:41 a.m. Eastern time in North America, or 0541 GMT.

“We saw the initial flare occurring and Read more…

Solar storms may wreak havoc on Earth in 2013: Scientists

The intensity of solar storms is expected to peak in 2013 and may devastate critical infrastructure like satellite communications, navigation systems and electrical transmission equipment, a top scientist has warned. Kathryn Sullivan, assistant secretary of the US National Oceanic and Atmospheric Administration, said countries should prepare for “potentially devastating effects” from solar storms which are caused by massive explosions on the sun.

Solar storms, according to scientists, release particles that can temporarily disable or permanently destroy fragile computer circuits, the Daily Mail reported.

Dr Sullivan, a former NASA astronaut who in 1984 became the first woman to walk in space, told a UN weather conference in Geneva that “it is not a question of if, but really a matter of when a major solar event could hit our planet”. She is not the only expert to issue a warning about the threat posed by solar storms. In February, astronomers warned that mankind is now more vulnerable to such an event than at any time in history — and that the planet should prepare for a global Hurricane Katrina-style disaster.

A massive solar eruption, they said, would send waves of radiation and charged particles to Earth, damaging satellite systems used for synchronising computers, airline  navigation and phone networks. If the storm is powerful enough it could even crash stock markets and cause power cuts that last weeks or months, experts told the American Association for the Advancement of Science.

The chances of a disruption from space are getting stronger because the sun is entering the most active period of its 11 to 12-year natural cycle. The world got a taster of the sun’s explosive power in February when the strongest solar eruption in five years sent a torrent of charged plasma hurtling towards the world at 580 miles per second. The storm created spectacular aurorae and disrupted radio communications.

Space storms are not new. The first major solar flare was recorded by British astronomer Richard Carrington in 1859. Other solar geomagnetic storms have been observed in recent decades. According to NASA, one huge solar flare in 1972 cut off long-distance telephone communication in the mid-western state of Illinois. Another similar flare in 1989 ‘provoked geomagnetic storms that disrupted electric power transmission’ and caused blackouts across the Canadian province of Quebec, the US space agency said.

Strong geomagnetic storm slams Earth on Wednesday

(TheWeatherSpace.com) — A solar storm is in progress right now with the highest Kp-index in a while being recorded.

The solar storm has a Kp-Index of 6, out of the 0-9 scale. This is higher than any previous solar storms, including the March event. What caused this without a flare?

“This solar storm is likely a flare caused storm,” TheWeatherSpace.com Senior Meteorologist Kevin Martin said. “It may not have been Earth directed but a blast from the sun a couple days ago hurled a lot of material into space. This material sometimes does not follow a straight line, but can curve with the influence of magnetic fields and gravity.”

Mid and High latitude observer should check out the skies and see if the northern and southern lights are around.

Martin is the scientist that thinks solar storms are triggers to earthquake activity. Will it cause a large quake? Time will tell but enjoy the skies for the next nine hours if it is clear, dark, and you are in a higher latitude.
