Sunspot 1339 has quieted since Nov. 3rd when it unleashed an X2-class solar flare. Nevertheless, it still poses a threat for powerful eruptions. The behemoth sunspot has a “beta-gamma-delta” magnetic field that harbors energy for more X-flares. Eruptions this weekend
Ok, people. We survived flyby of most popular "doomsday" Comet Elenin, now we facing another potential threat. Scientists assure us that we have nothing to worry about. Asteroid 2005 YU55 is the third close fly-by of a large asteroid to the Earth this year.
NOAA forecasters have upgraded the chance of X-class solar flares today to 20%. The source would be AR1339, one of the biggest sunspots in many years. The active region rotated over the sun’s eastern limb two days ago and now it is turning toward Earth.The Radio
A large sunspot group is rotating over the sun’s northeastern limb, possibly signaling an uptick in solar activity. Measuring some 40,000 km wide and at least twice that in length, the behemoth active region is an easy target for backyard solar
NASA scientists will have a unique observing opportunity with asteroid 2005 YU55, as the space rock “safely flies past Earth” at a distance slightly closer than the moon on Nov. 8, 2011.At the point of closest approach, the asteroid will be no closer than 201,700
The solar wind was at increased levels Tuesday morning and combined with a south tilting Bz, it stirred up a minor geomagnetic storm at high latitudes. Things have since returned to quieter levels.Solar activity increased to moderate levels Monday with three M-Class
Jupiter has been putting on quite a show in the night sky lately as it officially reached opposition on October 28, 2011, making it a target of many astrophotographers as the gas giant shows itself off big and bright in the night sky. This animation from amateur
An M1.1 Solar Flare peaked at 15:08 UTC Monday morning and was centered around a new region located on the Northeast Limb. Stay Tuned for increasing solar activity.The second and third M-Class Flares of the day has taken place around the new region hiding on the
According to various sources, a bright spot – possibly a developing storm – has been spotted on Uranus.Professional observers on October 27 reported a very bright cloud on Uranus, using the Gemini telescope, and need amateur confirmation if possible, to obta
Science has only just begun to understand how cyclical changes in the Sun effect Earth’s weather and climate. But the more technological human society grows, the more vulnerable we may become.Activity on the Sun is due to reach its peak around early 2014, so expect
