    Two years ago we were all going about our daily business blissfully unaware that our planet almost plunged into global catastrophe. A recent revelation by NASA explains how on July 23, 2012 Earth had a near miss with a solar flare, or Coronal Mass Ejection (CME), from the most powerful solar storm on the sun in over 150 years, but nobody decided to mention it. Err, what? Well that’s a sobering bit of news. “If it had hit, we would still be picking up the pieces,” says Daniel Baker of the University of Colorado. We managed to just avoid the...
  • 28 solar flares in the last seven days, and more may be coming(about time)

    The sun has erupted more than two dozen times over the last week, sending radiation and solar material hurtling through space - and scientists say more eruptions may be coming. This shouldn't be unusual. After all, we are technically at solar maximum, the peak of the 11-year cycle of the sun's activity. But this has been a noticeably mellow solar maximum, with the sun staying fairly quiet throughout the summer. So when our life-giving star suddenly let loose with 24 medium strength M-class solar flares and four significantly stronger X-class flares between Oct. 23 and Oct. 30, it felt like...

    Two NASA spacecraft are safe and sound, after the sun unleashed three intense back-to-back solar eruptions in their direction, scientists say. NASA's Messenger spacecraft in orbit around Mercury and the Stereo-A, which studies the sun from Earth orbit, suffered no damage from the passing solar storms. On April 20, the sun fired off a solar eruption that sent huge wave of plasma and charged particles, called a coronal mass ejection (CME), toward Mercury. The next day, the sun unleashed two more CMEs in the same direction, and managers from both the Messenger and Stereo missions were alerted of the potential...

    If Earth is struck by a large solar flare, some in the scientific community believe: The planet will be hit with a widespread loss of power. Air travel would be grounded. Nuclear plants would be crippled and without sufficient back-up power, dozens could meltdown. Satellites would be disabled, causing a serious loss of communication in all areas (military and civilian). Food and medicine would be in short supply, setting up the potential for food riots within days of an outage. The same scientists who believe that a large solar strike could lead to a very rapid societal breakdown say that...
  • Sun Erupts with Largest Solar Flare of the Cycle (August 9)

    Universe Today ^ | August 9, 2011 | Nancy Atkinson
    Early Tuesday morning (August 9, 2011,) the Sun erupted with the largest solar flare of Cycle 24, registering as an X7-class flare. This flare had an X-ray magnitude of X6.9, meaning it was more than 3 times larger than the previous largest flare of this solar cycle – the X2.2 that occurred on Feb 15, 2011, NASA said. The source was Sunspot 1263 which is nearing the western limb of the Sun, and because of its location, scientists do not anticipate that this explosion will hit Earth directly. Therefore, the impact on communications and electric grids will likely (and luckily)...

    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 am Eastern time in the United...

    The Crab Nebula has shocked astronomers by emitting an unprecedented blast of gamma rays, the highest-energy light in the Universe. The cause of the 12 April gamma-ray flare, described at the Third Fermi Symposium in Rome, is a total mystery. It seems to have come from a small area of the famous nebula, which is the wreckage from an exploded star. The object has long been considered a steady source of light, but the Fermi telescope hints at greater activity. The gamma-ray emission lasted for some six days, hitting levels 30 times higher than normal and varying at times from...

    The eruption hurled a coronal mass ejection (CME) into space, just missing a direct sun-Earth line. Forecasters expect the cloud to deliver no more than a glancing blow to our planet's magnetic field when it billows by on August 9th or 10th--not be a major space weather event. Future eruptions could turn out differently. Active region 1093 is rotating toward Earth. By the end of this weekend, we'll be in the line of fire if its magnetic fields become unstable again.

    Pilot Reports 'Missile' Fired at Jetliner Near LAX (11/28/05) FBI agents and Homeland Security officials spent the weekend investigating the report of a possible missile fired at an American Airlines plane taking off from Los Angeles International Airport. Sources tell ABC News the pilot of American Airlines Flight 621, en route to Chicago, radioed air traffic controllers after takeoff from LAX. He told them a missile had been fired at the aircraft and missed. The plane was over water when the pilot said he saw a smoke trail pass by the cockpit. FBI agents believe it was a flare or...

    A very strong class X17.1 solar flare exploded on the Sun at 17:40 UTC (1:40 pm EDT). This is a significant event. Very few solar flares ever reach the X-class rating, and far fewer ever exceed an X10 level. Only a few solar flares each solar cycle (a 10-year period) exceed an X10 rating. An X17 solar flare is 17 times more intense in x-rays than a class X1.0 (which is, by itself, a very energetic event). This particular event was strong enough to saturate one of the x-ray sensors on the GOES spacecraft and very nearly saturated both sensors....

    Earlier this month the Sun was as quiet as can be and free of the dark sunspots that generate eruptions of magnetic energy and hot gas. Now the solar surface is dotted with brooding blotches, and overnight a major flare erupted. The strong eruption, labeled an X2, involved an intense flash of radiation late Wednesday evening (East Coast time). All X-flares are considered major, and the associated number denotes just how strong they are. Major flares sometimes also hurl clouds of hot gas into space. These coronal mass ejections (CMEs) can threaten Earth-orbiting satellites and surface power grids, and also...

    A solar flare last Nov. 4 was at the time said to be at least X28 on a scale of intensity. That made it the strongest in modern times. And astronomers said at the time that it might have been stronger, but it saturated instruments on satellites used for analyzing the Sun's storms. Solar flares are intense outburst of solar radiation that include X-rays and are often accompanied by ejections of charged material in giant clouds. Now researchers at the University of Otago in New Zealand say the flare was an X45. (All X-flares are major, and the larger the...

  • Largest Solar Flare Ever Recorded (X30-X40) DOES have an Earth-Directed Component

    11/04/2003 6:04:19 PM PST · by John H K · 111 replies · 1,132+ views
    The X18+ solar flare has been associated with a high velocity FULL HALO coronal mass ejection. There IS an Earthward directed component. Estimated plane of sky velocity for this event is 2381 km/sec, although it is probable the true velocity is above 2400 km/sec because there is some evidence for acceleration of the CME. True x-ray intensity is unknown, but is probably near the X30 x-ray level (possibly between X30 and X40). VERY impressive event! Definitely one for the record books. We have no idea yet when this one might impact the Earth or how strong the impact might be....
