After two-week long transit around the far side of the Sun, Sunspot 1402 has returned into view in the northeast quadrant. Sunspot 1402 is now re-numbered as Sunspot 1419. This region is smaller than it was before, after two weeks of decay. On January 27 it unleashed
A new large sunspot is now rotating into view on the eastern limb. It just produced a minor C6.7 Solar Flare at 22:26 UTC Tuesday evening. Solar activity was moderate on Monday with one M-Class flare detected around Sunspot 1387. Numerous C-Class events were
Two new regions rotated into view on the eastern limb and were numbered 1363 and 1364 on Tuesday. Numerous low level C-Class flares have been detected within the past 24 hours around Sunspot 1362 and new Sunspot 1363.Region 1361 in the northern hemisphere is now
A line of sunspots stretching across the sun’s northern hemisphere appears to be an independent sequence of dark cores. A telescope tuned to the red glow of solar hydrogen, however, reveals something different. The sunspots are connected by sinuous filaments of
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.
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
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
A significant CME blasted off the sun today, Oct. 22nd, around 1100 UT. Analysts at the Goddard Space Weather Lab say the cloud is heading for Mars, due to hit the Red Planet on Oct. 26th. (movie, forecast track)While looking at the latest STEREO Ahead images,
At a NASA teleconference yesterday, researchers working with data from the Messenger spacecraft offered new evidence that gusts of solar wind are penetrating Mercury’s magnetic field and eroding material off the planet’s surface. The spacecraft has actually flown
Earth-orbiting satellites have detected a long-duration X1.4-class solar fare coming from a new sunspot on the sun’s eastern limb. The blast, which peaked at 1100 UT, produced a significant CME, but the cloud is not Earth-directed.
