After snow, sleet, and heavy wind all day, the clouds parted for a 2 hour display of spectacular pale green, blue, and purple auroras over the mountains of Reine.

Few things take our breath away so easily: Aurora Borealis Is One of Them

Few things take our breath away so easily, so seamlessly as images of our world. Sit back for the next two minutes and let the spectacle of our cosmos fill your senses. The deep emotional relationship we feel to our planet is evident.

GEOMAGNETIC STORM: a CME hit Earth’s magnetic field during the early hours of October 2nd

CME IMPACT, GEOMAGNETIC STORM

http://www.spaceweather.com

As expected, a CME hit Earth’s magnetic field during the early hours of October 2nd, sparking a G2-classgeomagnetic storm. In North America, auroras spilled across the Canadian border into more than a dozen northern-tier US states. Jason Brownlee sends this picture from Bend, Oregon:

“It’s not too often we get to see Northern Lights in Oregon,” says Brownlee. “It made a special appearance last night in the Cascade Mountains. “

The storm has subsided now, but it could flare up again. NOAA forecasters estimate a 50% chance of more polar geomagnetic storms as Earth passes through the wake of the CME on Oct. 3rd. Aurora alerts: textvoice.

South Africa in pole position for magnetic shift

Cape TownEarth’s magnetic field is undergoing significant shifts, and South Africa has front row seats to observe the changes.

Satellites and magnetic observatories have recorded stirrings in the magnetic field – some areas weakening, some strengthening – which suggest that our planet is headed for a reversal of its magnetic poles in the next few hundred years.

If that happens, compasses which usually point north will point south. Animals which use the magnetic field for navigation such as birds, whales and sharks will find it difficult to migrate along their usual routes. Our magnetic navigation systems will have to be recalibrated.

And while South Africans won’t be able to watch the aurora visible over the equator during the pole switch, we are in a prime position to monitor the process because we are situated between the two areas of greatest change in the magnetic field.

Just south-west of Cape Town is the region where the largest decrease was recorded by satellites between 1980 and 2001: -8 percent. And not too far east of South Africa is the region in the Indian Ocean where the largest increase was recorded, of +3 percent.

At the magnetic observatory in Hermanus, one of four in the country, the geomagnetic field has decreased by more than 20 percent since 1941.
