  • Photo: Giant sunspot sends its love to planet Earth

    04/14/2016 8:25:05 AM PDT · by BenLurkin · 17 replies
    The massive sunspot region now facing Earth, dubbed AR2529, has morphed into the shape of a heart. The lovely image was obtained by Karzaman Ahmad of the Langkawi National Observatory in Malaysia who shared it with the world at ... True to its form, the sunspot has proven to be a gentle giant so far, emitting few flares and only a couple weak coronal mass ejections. But such hearts can break, and what will follow is difficult to predict. It will spend about another week facing Earth.
  • Astronomy Picture of the Day -- The Sun in X-rays from NuSTAR

    Explanation: Why are the regions above sunspots so hot? Sunspots themselves are a bit cooler than the surrounding solar surface because the magnetic fields that create them reduce convective heating. It is therefore unusual that regions overhead -- even much higher up in the Sun's corona -- can be hundreds of times hotter. To help find the cause, NASA directed the Earth-orbiting Nuclear Spectroscopic Telescope Array (NuSTAR) satellite to point its very sensitive X-ray telescope at the Sun. Featured above is the Sun in ultraviolet light, shown in a red hue as taken by the orbiting Solar Dynamics Observatory (SDO)....

    BI - Scientific American ^ | 12-16-2014 | Monica Bobra
    Monica Bobra, Scientific American December 16, 2014A couple of months ago, the sun sported the largest sunspot we've seen in the last 24 years. This monstrous spot, visible to the naked eye (that is, without magnification, but with protective eyewear of course), launched more than 100 flares. The number of the spots on the sun ebbs and flows cyclically, every 11 years. Right now, the sun is in the most active part of this cycle: we're expecting lots of spots and lots of flares in the coming months. Usually, the media focuses on the destructive power of solar flares —...

    Explanation: Solar active region AR2192 was the largest recorded sunspot group of the last 24 years. Before rotating off the Earth-facing side of the Sun at the end of October, it produced a whopping six energetic X-class flares. Its most intense flare was captured on October 24 in this stunning view from the orbiting Solar Dynamics Observatory. The scene is a color combination of images made at three different wavelengths of extreme ultraviolet light; 193 angstroms shown in blue, 171 angstroms in white, and 304 angstroms in red. The emission, from highly ionized Iron and Helium atoms, traces magnetic field...

    Explanation: A New Moon joined giant sunspot group AR 2192 to dim the bright solar disk during Thursday's much anticipated partial solar eclipse. Visible from much of North America, the Moon's broad silhouette is captured in this extreme telephoto snapshot near eclipse maximum from Santa Cruz, California. About the size of Jupiter, the remarkable AR 2192 itself darkens a noticeable fraction of the Sun, near center and below the curved lunar limb.

    Explanation: As you (safely!) watched the progress of yesterday's partial solar eclipse, you probably also spotted a giant sunspot group. Captured in this sharp telescopic image from October 22nd the complex AR 2192 is beautiful to see, a sprawling solar active region comparable in size to the diameter of Jupiter. Like other smaller sunspot groups, AR 2192 is now crossing the Earth-facing side of the Sun and appears dark in visible light because it is cooler than the surrounding surface. Still, the energy stored in the region's twisted magnetic fields is enormous and has already generated powerful explosions, including two...

    During the past 48 hours, monster sunspot AR2192 has unleashed seven M-class solar flares. The most powerful of the bunch (Oct 22nd at 0159 UT) was an M9-class eruption that almost crossed the threshold into X-territory. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash. UV radiation from the flare ionized Earth's upper atmosphere, causing a brief blackout of HF radio communications on the dayside of Earth (e.g., parts of Asia and Australia). In addition, the explosion might have hurled a CME into space. Confirmation awaits the arrival of coronagraph data from the Solar and Heliospheric Observatory (SOHO). Stay tuned...

    According to AR2192 has grown considerably over the past few days and has the potential to unleash M- and X-class flares in our direction now that it’s moving into Earth-facing position. It’s currently many times larger than Earth and will likely get even bigger… in fact, during this week’s partial solar eclipse AR2192 should be visible with the naked (but not unprotected!) eye for viewers across much of North America.

    Properly shielded, it was very easy to see with the naked eye. Unlike some other naked eye sunspots, this one showed structure. The eastern end was darker, the western half grayer and more extended. Through a small telescope, the mix of dark umbras scattered amid weirdly sculpted penumbral “islands” was incredible to see. Photographs like the one above are wonderful documents, but witnessing this beautiful complex magnetic mess with your own eyes is another experience altogether. Region 2192 continues to grow and size and complexity and is now the largest sunspot group of solar cycle 24 which began in 2009...

    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: The source of the eruption is long-lived sunspot AR1967, now beginning its third trip across the Earthside of the sun. This region was an active producer of flares during its previous transits, and it looks like...

    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...

    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)...

    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.

    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."

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....

    Scientists Issue Unprecedented Forecast of Next Sunspot Cycle March 6, 2006 The next sunspot cycle will be 30 to 50 percent stronger than the last one, and begin as much as a year late, according to a breakthrough forecast using a computer model of solar dynamics developed by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo. The research results, funded by the National Science Foundation (NSF) and NASA, were published on-line on March 3 in the American Geophysical Union journal Geophysical Research Letters. Scientists now predict that the next cycle, known as Cycle 24, will produce...

Visible above is a close-up picture of a sunspot, a depression on the Sun's face that is slightly cooler and less luminous than the rest of the Sun. The Sun's complex magnetic field creates this cool region by inhibiting hot material from...

    A coronal mass ejection (CME) is racing toward Earth and it could spark a severe geomagnetic storm when it arrives--perhaps tonight (Sept. 14th and 15th). People everywhere should be alert for auroras.
  • Powerful Solar Storm to Hit Earth by Wednesday

    A huge sunspot kicked up a powerful flare Monday that could spark colorful sky lights above Earth Tuesday night or early Wednesday. The flare was classified as X-3. All X-class flares are considered major, with the number indicated a degree of severity. Its radiation traveled at light-speed, arriving at Earth within minutes and, along the way, swamping a detector on the Solar and Heliospheric Observatory (SOHO) spacecraft, which monitors the Sun and its storms. Along with the flare came a billowing cloud of charge particles known as a coronal mass ejection (CME). Traveling at millions of miles per hour, CMEs...

    The K7RA Solar UpdateSEATTLE, WA, Jun 11, 2004 Solar activity remains low. As the sunspot cycle declines, we are inevitably headed toward a year or two of quiet sun. The sunspot minimum still is several years away, however. This week average daily sunspot numbers were up slightly by more than 7 points to 68.3. Average daily solar flux was down nearly 10 points to 87.4. Geomagnetic conditions remained quiet to slightly unsettled. The chance of any geomagnetic upset this weekend seems very remote. The sun is nearly blank, but as of June 10, two sunspots were peeking around the edge...

    Another remarkable solar flare has erupted from giant sunspot 486--an X8-class blast at 1725 UT on Nov. 2nd. Because the sunspot is nearing the sun's western limb, this explosion was not aimed squarely at Earth. Even so, a coronal mass ejection (CME) is heading our way. Auroras could appear on Nov. 3rd or 4th when the fast-moving cloud delivers a glancing blow to Earth's magnetic field. Visit for more information and images.

    SOLAR BLAST: Twisted magnetic fields above giant sunspot 30 erupted on Monday, July 15th, at 2005 UT. The explosion sparked a powerful X3-class solar flare and hurled a coronal mass ejection (CME, pictured right) into space. Although the CME was not squarely Earth-directed, it might nevertheless buffet our planet's magnetic field as early as July 16th (although the 17th is more likely). NOAA forecasters estimate a 10% chance of severe geomagnetic activity on Wednesday; sky watchers should be alert for auroras.

    So, the eco-whackos at EPA sent out one of their regularly scheduled "Administrative Reports" on global warming to the United Nations again. This time, some desk- bound, far-left resident bureaucrat also sent the "report" to the media as an "official" administrative response. . . . Yawn. . . . Problem is, they forgot to show it to the adults in the administration first. So, the "report" received a couple days free play by the liberal media before President Bush put the kibosh on that foolishness. Perhaps a little about the public schizophrenia of these bureaucrats and their counterparts could be...
