Solar activity at start of December

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

Earth currents in Norway caused by solar wind stream

A solar wind stream is buffeting Earth's magnetic field and this is causing electrical currents to flow in the Earth itself at high latitudes.Rob Stammes sends this report from the Polar Light Center in Lofoten, Norway to "Today, a magnetic

CME impact generates wonderful auroras

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 - K index rising, watch for auroras!!!

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

Radiation storm and CME heading toward Earth, geomagnetic storm and aurora events expected

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

Beautifull auroras and the interplanetary magnetic field

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

Double eruption on Sun

On October 1st around 10:17 UT, widely-spaced sunspots 1302 and 1305 erupted in quick succession, revealing a long-distance entanglement which was not obvious before. NASA's Solar Dynamics Observatory (SDO) recorded the movie of the double blast:Since it was

Geomagnetic storm continues

New sunspot AR1295 is emerging over the sun's northeastern limb and crackling with solar flares. The strongest so far, a C9.9-category blast, did something remarkable. Click on the arrow to watch an extreme ultraviolet movie from NASA's Solar Dynamics

Wonderful weekend auroras for start of May

It has been a good weekend for northern sky watchers. A solar wind stream hit Earth's magnetic field on Saturday, sparking two days of auroras around the Arctic Circle. In Alberta, Canada, this morning, the month of May began with a psychedelic sky:High-latitude

Geomagnetic storm in progress (April 30, 2012)

A solar wind stream hit Earth's magnetic field during the early hours of April 30th, sparking a high-latitude geomagnetic storm (slowly subsiding). In the United States, auroras descended as far south as Marquette, Michigan, where Shawn Malone took this picture before
