The CME launched toward Earth by yesterday's X-flare is moving faster than originally thought. Analysts at the Goddard Space Weather Lab have revised their forecast accordingly, advancing the cloud's expected arrival time to 09:17 UT (5:17 am EDT) on Saturday, July 14th. Weekend auroras are likely.


SOUTH POLE AURORAS: In a possible preview of the light show to come, bright auroras have been dancing over Earth's south pole. Robert Schwarz took this picture on July 12th from the grounds of the Amundsen-Scott South Pole Station:




"Yesterday we had some of the best auroras I've seen," says Schwarz.

Despite its high latitude, the South Pole is not always a good place to see the lights because it is often located in the "doughnut hole" of the aurora oval. July 12th was an exception: "Look carefully at the picture and you can see the actual Pole in the foreground" Schwarz points out.

NOAA forecasters estimate a 55% chance of strong polar geeomagnetic storms on July 14th when a CME is expected to crash into Earth's magnetic field. More South Pole auroras could be in the offing.

The radiation storm, in progress, ranks "S1" on NOAA space weather scales, which means it poses no serious threat to satellites or astronauts. This could change if the storm continues to intensify. Stay tuned.

Hi again. It seems that we will not see the auroras in my area, not north enough. I'll have to ask my MI friend to look up and see if they are visible where she lives.

I am off to look at the link to LowerCal's for the photos.

Hey darling... thanks for dropping in to this tiny corner of WU.
I want to share that another member was able to collect a few photos after the storm.

I am looking right now for some photo to post up in here..I was too far south of the North Pole down in Mississippi USA to catch any bit of the wonderful colors of the night sky.

Good morning. I'll be back shortly to read about the auroras. I have never seen one but I do love looking at the photos of them and the documentaries about them. Just beautiful!
