Forecasters at the NOAA Space Environment Center in Boulder, Colo., observed a geomagnetic storm on Sunday, May 15, which they classified as an extreme event, measuring G-5—the highest level—on the NOAA Space Weather Scales.

"This event registered a 9 on the K-Index, which measures the maximum deviation of the Earth's magnetic field in a given three-hour period," said Gayle Nelson, lead operations specialist at NOAA Space Environment Center. "The scale ranges from 0 to 9, with 9 being the highest. This was a significant event."

Possible impacts from such a geomagnetic storm include widespread power system voltage control problems; some grid systems may experience complete collapse or blackouts. Transformers may experience damage. Spacecraft operations may experience extensive surface charging; problems with orientation; uplink/downlink and tracking satellites. Satellite navigation may be degraded for days, and low-frequency radio navigation can be out for hours. Reports received by the NOAA Space Environment Center indicate that such impacts have been observed in the United States.

NOAA forecasters said the probability of another major event of this type is unlikely, however, other minor level (G-1) geomagnetic storms are possible within the next 24 hours.

This event was forecast by NOAA as the result of a solar flare that occurred on Friday, May 13.

The NOAA Space Environment Center, one of the NOAA National Centers for Environmental Prediction, is home to the nation's early warning system for solar activities that directly affect people and equipment on Earth and in space. The NOAA Space Environment Center’s 24/7 around-the-clock operations are critical in protecting space and ground-based assets. Through the SEC, NOAA and the U.S. Air Force jointly operate the space weather operations center that continuously monitors, analyzes and forecasts the environment between the sun and Earth. In addition to the data gathered from NOAA and NASA satellites, the center receives real-time solar and geophysical information from ground-based observatories around the world. NOAA space weather forecasters use the data to predict solar and geomagnetic activity and issue worldwide alerts of extreme events.

NOAA, an agency of the U.S. Department of Commerce, is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and providing environmental stewardship of the nation's coastal and marine resources.

I wonder what the actual experienced events were...?

Well, it's actually all over and has been for hours.

I was going to post on it very late last night but I was bitter I was clouded in and wouldn't see any aurora, and had to go to sleep anyway, so I didn't...wish I had, there was a bright aurora viewed even in Southern California, hope people interested didn't miss it.

Boy, based on my background in science from my lifelong love for Marvel Comics, I'd say there's a decent chance we got a few new super heroes and supper villains coming! :-)

Please, everyone who reads this thread, go out an stock up on bread, milk, the staples, you know, because the world is going to end.

Watch for this theme on the MSM (LM) tomorrow.

I'm sure Art Bell will be blabbing about this tonight ... and Ed Dames will claim it as the "Kill Shot."

I was wondering how the Spurs lost so badly in the NBA playoff game with Seattle tonight. I think I now have an explanation.

Interesting...I had to go in to work yesterday morning, Sat the 15th...Many machinery lines apparently encountered temporary electrical failures and shut down but came right back on...Maintenance crew searched everywhere for a problem but could find none...I had forgotten about the warning...

From the DX listeners club:

"The extreme southwards IMF between 05:30 and 06:10 UTC caused extremely severe geomagnetic storming. Boulder recorded magnetic deviations of 682 nT, far exceeding what is required to achieve a K index of 9."


"Long distance low and medium frequency (below 2 MHz) propagation along east-west paths over high and upper middle latitudes is useless. Propagation along long distance north-south paths is poor. Trans Atlantic propagation conditions are normally monitored every night on 1470 kHz. Dominant station tonight: Radio Cristal del Uruguay. Only a few other stations, like Rádio Clube Paranaense on 1430 and Rádio 9 de Julho on 1600 kHz were heard on other frequencies."

We still may see extremes for the next 30 hours or so.

Bump. Biggest news of the night, short of the Newsweek fiasco.
