More Signs Of The Sun Slowing Down | Watts Up With That?
In my post from yesterday , I highlighted a paragraph from a NASA press release which touched on one of the final findings of the soon to be ended Ulysses spacecraft mission to study the sun: “Ulysses ends its career after revealing that the magnetic field emanating from the sun’s poles is much weaker than previously observed. This could mean the upcoming solar maximum period will be less intense than in recent history. “
Strange emissions by sun are mutating matter… | Project World Awareness
For months mounting fear has driven researchers to wring their hands over the approaching solar storms. Some have predicted devastating solar tsunamis that could wipe away our advanced technology, others voiced dire warnings that violent explosions on the surface of the sun could reach out to Earth, breach our magnetic field, and expose billions to high intensity X-rays and other deadly forms of cancer-causing radiation. Now evidence has surfaced that something potentially more dangerous is happening deep within the hidden core of our life-giving star: never-before-seen particles—or some mysterious force—is being shot out from the sun and it’s hitting Earth. Alarmed physicists first became aware of this threat over the past several years. Initially dismissed as an anomaly, now frantic scientists are shooting e-mails back and forth to colleagues across the world attempting to grasp exactly what is happening to the sun.

2012: Magnetic Pole Reversal Happens All The (Geologic) Time
Scientists understand that Earth's magnetic field has flipped its polarity many times over the millennia. In other words, if you were alive about 800,000 years ago, and facing what we call north with a magnetic compass in your hand, the needle would point to 'south.' This is because a magnetic compass is calibrated based on Earth's poles. The N-S markings of a compass would be 180 degrees wrong if the polarity of today's magnetic field were reversed.Earlier, it was stated that the current Solar Radiation Storm was the largest since May 2005, when the 10 MeV protons exceeded over 3000 PFU. This was not correct. At the time of the earlier post, this current Storm was the biggest since January 2005, when the 10 MeV flux was 5040 pfu. After the arrival of the CME earlier today, the 10 MeV flux again increased and we were at around 6300 pfu.
Another LDE M Flare and 2 CME's - Jan 23 2012
Space Weather Research - University of Bradford
Solar images, along with other observational data, are very important for solar physicists and space weather researchers aiming to understand the way the Sun works and affects Earth. Much of the data available in solar images are catalogued in terms of solar features and solar activities by different organizations around the world in order to provide researchers with historical changes of the Sun to facilitate research.Radiowave Propagation Center: forecast + current sunspot cycle activity, space weather, geomagnetic conditions
Hot: STD Space Weather Course This is an excellent self-study course on Space Weather and Radio Propagation . This is a very in-depth and rich course that will equip you with the knowledge you need for understanding Space Weather, the ionosphere, how radio signals propagate via the ionosphere, and much more. Check it out! Check out the ACE-HF propagation software - the latest is version 2.05.
The Watchers - M3.2 solar blast from Sunspot 1402 produced Earth-directed CME
The long-duration blast at active region 1402 produced M3.2 solar flare and CME which is heading toward Earth. This was two-wave flare and first CME wave was overtaken by the 2nd wave due to its higher speed velocity.The major bulk of the plasma cloud appears to be directed north. A minor R1 Level Radio Blackout resulted. Active Regions 1401 and 1402, positioned near the center of the disk, dominate the x-ray imagery today. Expect additional R1 (Minor) Radio Blackouts from flares, and given their location, an eruption of a CME in the near future would certainly have an impact on the earth’s magnetic field.
