A radiation storm that began on Nov. 26th when a magnetic filament erupted on the sun is subsiding. Nevertheless, the Earth-effects are just beginning. The same explosion that caused the radiation storm also hurled a CME into space at about 930 km/s (2 million mph).
A solar radiation storm is in progressaround Earth. At the moment, the storm is classified as minor, which means it has little effect on our planet other than to disturb HF radio transmissions at high latitudes. Bigger effects, however, may be in the offing. The
A solar radiation storm is in progress around Earth. At the moment, the storm is classified as minor, which means it has little effect on Earth other than to disturb HF radio transmissions at high latitudes. Energetic protons, which make up the bulk of the storm,
Earlier today, Nov. 25th, the new Moon passed in front of the sun, slightly off-center, producing a partial solar eclipse visible from Antarctica, Tasmania, and parts of South Africa and New Zealand. Maximum coverage occurred about 100 miles off the coast of
Officially, the odds of a geomagnetic storm on Nov. 24th were small but dedicated aurora watchers still had some opportunity to take some nice images of beautifull sky game. Auroras have been flickering around the Arctic Circle for several days. These displays are not
Earth-facing sunspot 1356 has developed a “beta-gamma” magnetic field that harbors energy for M-class solar flares. NOAA forecasters estimate a 30% chance of such an eruption during the next 24 hours.A bright Coronal Mass Ejection (CME) is seen in the latest Lasco
A possible filament eruption in the northwest quadrant on Sunday has generated a slow moving Coronal Mass Ejection (CME). You can watch the STEREO Ahead COR2 movie below and it looks like a portion of this cloud may be Earth directed. Stay tuned for more
It’s one of the biggest things in the entire solar system. A dark filament of magnetism measuring more than 800,000 km from end to end is sprawled diagonally across the face of the sun. NASA’s Solar Dynamics Observatory took this ultraviolet picture of the structure
A magnetic prominence dancing along the sun’s southeastern limb became unstable on Nov. 15th and slowly erupted. NASA’s Solar Dynamics Observatory recorded the coronal mass ejection (CME), which unfolded over a period of thirteen hours: The eruption hurled a cloud
A pair of M-Class flares took place on Tuesday morning. The first one registered M1.2 and was centered around Sunspot 1348 which is located near the northwest limb. The second event at 12:43 UTC peaked at M1.9 and was located around Sunspot 1346 in the southern
