M-class solar flare reaching M1.1 took place at 13:35 UTC Wednesday morning around Sunspot 1342 which is located in the northeast quadrant. It now looks like a Coronal Mass Ejection (CME) resulted and a portion of it may be Earth Directed. A region located on the
Sunspot 1339 is indeed one of the largest Sunspot groups in years. Here is a size comparison of 1339 vs. a couple of the largest Sunspots from Cycle 23. Sunspot 9393 was responsible for the second largest Solar Flare in recorded history (X20) back in April 2001.
Those of us without access to the world's biggest radio telescopes still have a chance to spot 2005 YU55 as it zips past Earth. The asteroid will be brightest in the sky a few hours after its closest approach and should be visible with decent equipment under clear,
The asteroid 2005 YU55, which is about 400 meters (1,300 feet) in diameter, will make its closest approach to Earth at 23:28 UTC (23:28 GMT, 6:28 p.m. EST, 3:28 PST) today. At that point, the space rock will be traveling at about 46,671 km (29,000 mph) with distance
The Northern Hemisphere is entering the quarter of the year with the least amount of daylight, known as solar winter.As the Northern Hemisphere is tilted away from the direct rays of the sun, over 50 percent of the hemisphere is in darkness at any one time. Colder
Discovered nearly six years ago by Robert McMillan at Steward Observatory’s Spacewatch Telescope in Arizona, 2005 YU55 has been this way before. In April 2010 it passed close enough for detailed radar probing by the giant radio dish at Arecibo, Puerto Rico. It
If you look in sun direction in time of sunset you could see the largest sunspots since 2005 . Active region 1339 is now visible from the Earth. These huge sunspots have been slowly rotating to face the Earth since November 3, 2011. The largest of these sunspots,
NASA radars are monitoring 2005 YU55, an asteroid the size of an aircraft carrier, as it heads for a Nov. 8th flyby of the Earth-Moon system. There is no danger to our planet. At closest approach on Tuesday at 3:28 pm PST, the 400m-wide space rock will be 324,600
A Guide for Solar Watchers pt.1 – Sun basics
For all those who don't quit understand what is happening with our Sun and what is space weather we decided to make A Guide for Solar Watchers. We will start with solar basics – structure, characteristics, solar
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
