RARE VIDEOS OF STEVE: On April 10th, a G1-class geomagnetic storm was brewing over Canada as a stream of solar wind buffeted Earth's magnetic field. Matthew Wheeler of Robson Valley, British Columbia, stepped outside to see what was up--and STEVE appeared. "My dog barked at it for the entire hour it was visible," says Wheeler. "It was flowing like a river at astonishing speed." Click to play his must-see video:
STEVE may look like an aurora, but it is not. For one thing, it is soft purple, not green like typical auroras. And it has its own special form--tightly collimated into a narrow ribbon that can bisect the entire sky.
Researchers are only beginning to understand the phenomenon--aided by a chance encounter between STEVE and a European satellite a few years ago. In situ measurements revealed that STEVE is a hot (3000 degrees C) ribbon of ionized gas slicing through Earth's upper atmosphere some 300 km above the ground. It appears unpredictably during some, but not all, geomagnetic storms.
Another video--"my best yet," says Wheeler--shows the beautiful interaction between the soft-purple ribbon and nearby green "picket fence" auroras
"The purple ribbon was moving much faster than the green pickets," says Wheeler. "And while their forms varied from smooth to ragged and back again, their path across the sky was almost constant for the whole hour--as it has since I first noticed STEVE over this valley in the 1980s."
Does STEVE really make dogs bark? "Mine does," says Wheeler. "In addition to barking at STEVE, my giant Akbash astronomy dog, Patch, has barked at the space station since he was a pup, and proudly seen it off the farm every time. He is also a valuable spotter of meteor showers. When I hear him barking upwards, it is time to go outside."
Florence isn't the only one. There are more hurricanes brewing
By Jay Croft, CNN / Mon September 10, 2018
(CNN)All eyes are on Hurricane Florence and its path toward the Carolinas, but other hurricanes are brewing as well. And the timing couldn't be more apt: Monday was the peak of the Atlantic hurricane season, when storm activity has historically been at its highest.

Here is an all sky view of the 45 minute Steve event as seen from Isle Royale National Park on 09.13.18. The fisheye lens captured the scale of this event as the picket fence rays of light stretched from NE to overhead and to the south but I was pushing the limits of the gear limited by f.4. The rays were intense and very bright. Look for the big dipper at bottom of frame for scale.
Welcome to the December Solstice, the first day of winter in planet Earth's northern hemisphere and summer in the south. To celebrate, consider this extraordinary display of beautiful solar ice halos! More common than rainbows, simple ice halos can be easy to spot, especially if you can shade your eyes from direct sunlight. Still it's extremely rare to see anything close to the complex of halos present in this astounding scene. Captured at lunchtime on a cold December 14 near Utendal, Sweden the image includes the relatively ordinary 22 degree halo, sundogs (parhelia) and sun pillars. The extensive array of rarer halos has been identified along with previously unknown features. All the patterns are generated as sunlight (or moonlight) is reflected and refracted in flat six-sided water ice crystals in Earth's atmosphere. In this case, likely local contributors to the atmospheric ice crystals are snow making machines operating at a nearby ski center.
Imagine living and working in darkness, 24 hours a day for 6 months out of every year. Robert Schwarz does just that. He's a professional telescope operator for the Keck Telescope Array at the Amundsen-Scott South Pole Station. And his hobby is astrophotography. For the past 14 winters, he has been taking pictures of the south polar night, witnessing scenes unlike anyplace else on Earth. His work is highlighted in a newly-released video entitled "South Pole | Night In Antarctica."
A longtime contributor to Spaceweather.com, Robert Schwarz is a pioneer in cold-weather astrophotography. At the South Pole, temperatures routinely drop below -70o C. Modern DSLR cameras are not made for such temperatures. LCD displays freeze instantly, mirror mechanisms get stuck, batteries fail, and time-lapse sequences often end after only 30 or 40 frames. To mitigate these problems, Robert has developed heated camera housings and motorized trackers with insulation, allowing his optics to follow the pirouette of the stars overhead even in deep Antarctic cold.
Cinematographers Christoph Malin and Martin Heck created the video using a year's worth of Schwarz's unique footage. They're looking forward to more. Right now, Robert is traveling to the South Pole for a record-setting 15th "overwinter," and of course he's taking his cameras. Stay tuned!
