Solar Flares Could Hit GPS
It might be time to review these skills in light of the VOR sunspot activity that had the potential to disrupt GPS signals, Friday and Saturday. Thursday, the sun sent a significant burst of electromagnetic energy to the earth after sunspot 1261 spat three major solar flares. The eruption was estimated at three on a scale of five, and that's enough to make a GPS device loses its way. It is especially hard on the units as high-precision gears aviation WAAS. The worst was expected to be more in the end Saturday, but there could be more solar storms to come.
After a prolonged period of unusual sleepiness, the sun appears to be waking up as it moves to the apex of its 11-year activity cycle. More big flares are possible, even likely, and if they get bigger than those on Thursday they can cause real problems. "In a solar cycle there are perhaps 10 or 20 events of this size," Brian J. Anderson, a research physicist at the Johns Hopkins University's Applied Physics Lab told the Baltimore Sun . "This is not a once-in-a-century type of thing. I'd say it's the first really strong one we're seeing out of this solar cycle.

Aurora displays, which are seen as arcs of light extending hundreds of miles on the horizon, are most frequent at times of immense sunspot activity. Scientists say Earth will witness a peak of sunspots activity around 2013. As the Sun enters a phase of
Sunspot activity dipped over this past week, but now it on its way back up. On July 20, five sunspot groups were visible, but on July 21, only groups 1251, 1254 and 1259 remained. On July 24, new sunspot group 1260 appeared, and the next day,
A CME happens when the outer solar magnetic fields are closed, often above sunspot groups, and the confined solar atmosphere can suddenly and violently release bubbles of gas and magnetic fields. The strongest solar storm on record is called the
Image Martin McKenna (nightskyhunter.com) NOAA's Space Weather Prediction Center has announced that solar activity is likely to remain moderate to high for the next two days (05-06 Aug) after an active sunspot unleashed a significant M-class solar
Between 1957 and 1958 sunspot activity hit a peak ...
Between 1957 and 1958, sunspot activity hit a peak that drove both scientists and governments around the globe to descend upond Antarctica where they could use its unique view of the southern hole in the Earth’s magnetic field to study the earth as it was bombarded by solar radiation from sunspot activity. Over 60 different countries took part and set up camps all around Antarctica. This movement, and the cooperation among the scientists in this community were a drving factor in the Antarctic Treaty, an amazing international agreement. Help on antarctica travel brochure is easy to get.
In 1959, this treaty was ratified by nations that had specific investments in Antarctica. It made it so the Antarctica could only be used for positive ventures. Nuclear experimentation was prohibited, as was the discarding of the radioactive waste generated. While some military activities, they are strictly limited to the logistical support of scientific activities. Any claims from differing countries were set aside in the nature of cooperation.
@ It's probably the Sun spot activity ;-)
You might be able to spot aurorae in the sky tonight, due to sun activity ?
@ Sun spot activity was at record lows in 2010, yet was globally the hottest & wettest year recorded
