Geomagnetic storm in progress, gigantic solar prominences
Amateur astronomers around the world are reporting strong activity on the limb of the sun. The prominences on June 4th were gigantic. Prominences are clouds of hot plasma
Comet hit the Sun?
A comet just discovered by amateur astronomer Sergey Shurpakov is diving past the sun today, and it will probably not survive. Click here to view a movie of the death plunge recorded by the Solar and Heliospheric Observatory–and check back for updates in the hours
Spectacular CME, active region approaching Earth
A sunspot located just behind the sun’s eastern limb erupted during the waning hours of May 9th, hurling a spectacular coronal mass ejection into space: movie. NASA’s Solar Dynamics Observatory photographed hot magnetic loops towering over the edge of the sun in the
Fast growing sunspot 1199
New sunspot 1199 is growing rapidly in the sun’s northern hemisphere, ballooning in area by more than a factor of five during the last 24 hours. If the expansion continues apace, this active region could soon pose a threat for flares. Stay tuned. (SpaceWeather)
Big sunspot 1195 harbors energy for M-class solar flares
This detailed image of sunspot 1195 looks like it was taken by one of NASA’s most advanced space telescopes. In fact, it comes from someone’s backyard in the Netherlands. Scroll down for the full story, and carefully examine the starscape as you
Coming of big troubled sunspot region
A big sunspot is emerging over the sun’s southeastern limb, and it is crackling with activity. NASA’s Solar Dynamics Observatory recorded a surge of extreme ultraviolet radiation from the sunspot’s magnetic canopy on March 21st:This appears to be the return of old
Seven M-class flares today
Several M-Class flares (7) took place during the day on Monday. Sunspot 1165 which is located in the southern hemisphere is in the process of rotating onto the western limb and will soon be out of direct earth view. Sunspot 1164 which is in the northern hemisphere
Visible sunspots and equinox conjunction
Sunspots 1164 and 1166 are so large, people are noticing them at sunrise and sunset when the sun is dimmed by clouds and haze. The dark cores of these regions are many times wider than Earth, so they are conspicuous even from a distance of 93 million miles.
NASA-sponsored research explains missing sunspots
WASHINGTON — NASA-sponsored research has resulted in the first computer model that explains the recent period of decreased solar activity during the sun’s 11-year cycle.This recent solar minimum, a period characterized by a lower frequency of sunspots and solar
Missing sunspots gathered NASA’s scientist for briefing
NASA said it has rescheduled a media teleconference to Wednesday 2 pm EST to discuss the first computer model that explains the recent period of decreased solar activity during the sun’s 11-year cycle.The recent solar minimum, a period characterized by a lower
