    Fierce solar blasts that could have badly damaged electrical grids and disabled satellites in space narrowly missed Earth in 2012, U.S. researchers said on Wednesday. The bursts would have wreaked havoc on the Earth's magnetic field, matching the severity of the 1859 Carrington event, the largest solar magnetic storm ever reported on the planet. That blast knocked out the telegraph system across the United States, according to University of California, Berkeley research physicist Janet Luhmann. "Had it hit Earth, it probably would have been like the big one in 1859, but the effect today, with our modern technologies, would have...

    X-FLARE! Long-lived sunspot AR1967 returned to the Earthside of the sun on Feb. 25th and promptly erupted, producing an X4.9-class solar flare. This is the strongest flare of the year so far and one of the strongest of the current solar cycle. A movie from NASA's Solar Dynamics Observatory shows the explosion hurling a loop of hot plasma away from the blast site: http://spaceweather.com/images2014/25feb14/redflare3_strip4.gif The source of the eruption is long-lived sunspot AR1967, now beginning its third trip across the Earthside of the sun.

    Explanation: It was a quiet day on the Sun. The above image shows, however, that even during off days the Sun's surface is a busy place. Shown in ultraviolet light, the relatively cool dark regions have temperatures of thousands of degrees Celsius. Large sunspot group AR 9169 from the last solar cycle is visible as the bright area near the horizon. The bright glowing gas flowing around the sunspots has a temperature of over one million degrees Celsius. The reason for the high temperatures is unknown but thought to be related to the rapidly changing magnetic field loops that channel...

    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...

    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)...

    The theory that signs of global warming could be the result of sunspots rather than carbon dioxide emissions caused by humans has come under attack from climate scientists. Sceptics about man-made climate change frequently cite research apparently linking natural variations in solar activity with fluctuations in temperatures on Earth. The alternative explanation was the centrepiece of The Great Global Warming Swindle, a 2007 Channel 4 documentary which provoked fierce argument. It is based on the work of Prof Eigil Friis-Christensen and Henrik Svensmark of the of the Danish National Space Centre, who both published studies in the 1990s appearing to...

    ASTRONOMERS are claiming that Earth is witnessing the biggest and most powerful Sunspot ever seen and the sunspot is yet to peak in intensity. A sunspot is a magnetic storm on the surface of the sun and the area of the spot is colder than the normal surface.

The size of a sunspot varies, ranging from the size of the moon to 65 times larger than the size of earth and lasts for about a month then fades away. This newest sunspot is thought...

    Astronomers who count sunspots have announced that 2008 is now the "blankest year" of the Space Age. As of Sept. 27, 2008, the sun had been blank, i.e., had no visible sunspots, on 200 days of the year. To find a year with more blank suns, you have to go back to 1954, three years before the launch of Sputnik, when the sun was blank 241 times. "Sunspot counts are at a 50-year low," says solar physicist David Hathaway of the NASA Marshall Space Flight Center. "We're experiencing a deep minimum of the solar cycle."

    It was a curious exercise, watching environmentalists and weathermen turn Global Warming into a universal evil: the average temperature of the world is rather chilly. Virtually all animals and plants do better in a warmer climate than a cooler one. And not just because of the temperature: a warmer climate means more rain showers because water vapor increases. This also means less cyclonic storms, contrary to public perception. But not to be deterred from turning a very active sunspot cycle into good news--in spite of record harvests throughout the world between 1995 and 2005--nut jobs, hysterics, Luddites, and opportunists...

    WASHINGTON - A new solar cycle is under way. The National Oceanic and Atmospheric Administration said Friday that the first sunspot of a new 11-year cycle has appeared in the sun's northern hemisphere. The frequency of sunspots rises and falls during these cycles, and the start of a new cycle indicates they are likely to begin increasing. Sunspots, areas of intense magnetic activity on the sun, can affect Earth by disrupting electrical grids, airline and military communications, GPS signals and even cell phones, the agency said. During periods of intense sunspot activity, known as solar storms, highly charged radiation from...

    RADIATION STORM:A radiation storm is underway. Based on the energy and number of solar protons streaming past Earth, NOAA (National Oceanic and Atmospheric Administration)ranks the storm as category S3 (Strong): satellites may experience single-event upsets and astronauts should practice "radiation avoidance." The rush of protons may be a sign of an approaching CME (coronal mass ejection). Protons are accelerated in shock waves at the leading-edge of CMEs, so when the proton count rises, we can guess that a CME is en route. Northern sky watchers should remain alert for auroras, which could flare up if and when a CME arrives....

NOAA forecasters estimate a 10% chance of severe geomagnetic activity on Wednesday; sky watchers should be alert for auroras.

Perhaps a little about the public schizophrenia of these bureaucrats and their counterparts could be...
