Sunspot AR1363 is growing rapidly, more than doubling in size since Friday. A 48-hour movie from NASA’s SOlar Dynamic Observatory shows the expansion:The active region has a “beta-gamma” magnetic field that harbors energy for M-class solar flares. Because of
A magnetic filament rapidly erupted on the sun today. Between 10:30 and 11:30 UTC, observers in Europe watched tendrils of hot plasma rocket away from the sun’s NW limb. Debris from the explosion is not expected to hit Earth according to SpaceWeather. Solar
With no strong flares this week, the sun’s x-ray output has nearly flatlined. The solar activity is quiet and is expected to continue for another 24+ hours. NOAA forecasters estimate a mere 20% chance of M-class solar flares.C-Class flares continue to be detected
With no sunspots producing strong flares, the sun is officially quiet. But although the sun is officialy “quiet” multiple C-Class flares have been detected within the past 24 hours. C-Class flares continue to be detected around various locations on the visible solar
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
As predicted by analysts at the Goddard Space Weather Lab, a coronal mass ejection (CME) hit Earth's magnetic field at approximately 2145 UT on Nov. 28th. The impact was weaker than expected, but it still produced bright auroras around the Arctic Circle.Planetary K-
A coronal mass ejection (CME) hit Earth’s magnetic field at approximately 2145 UTC on Nov. 28th. The impact was relatively weak and did not spark a strong geomagnetic storm yet. Kp index is at level 4.Solar
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
