A coronal mass ejection (CME, movie) that swept past Mercury on Nov. 13th will likely hit Venus later today. Because Venus has no global magnetic field to protect it, the impact could erode material directly from the top of the planet’s atmosphere. Venus has atmosphere
The latest time-lapse sequence of photographs by ISS Space crew shows period fromAugust to October, 2011 with amazing auroras. Images was put together by Michael König. These views are taken with a special low-light 4K-camera now on the Space Station.You can see
There haven’t been any strong solar flares in days. Nevertheless, some impressive activity is underway on the sun. For one thing, an enormous wall of plasma is towering over the sun’s southeastern horizon. Huge solar filament is the biggest in a longer time period. A
Yesterday, Nov. 9th around 1330 UT, a magnetic filament in the vicinity of sunspot complex 1342-1343 erupted, producing a M1-class solar flare and hurling a CME into space. The Solar and Heliospheric Observatory recorded the progress of the expanding plasma
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.
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,
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
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
