RARE BLUE AURORAS OVER CANADA: A solar wind stream hit Earth during the early hours of July 28th. First contact rattled Earth's magnetic field and sparked rare blue auroras over Canada. Joel Weatherly sends this picture of the colourful spray just outside Edmonton:

WHAT A 'MINOR' IMPACT LOOKS LIKE: A minor CME is expected to hit Earth on July 3rd. What will that look like? We got a preview on June 30th when a similar shock wave arrived. Harlan Thomas of Alberta, Canada, recorded the display:

CME SPARKS STRONG GEOMAGNETIC STORM: A coronal mass ejection (CME) hit Earth's magnetic field during the early hours of May 12th, sparking the strongest geomagnetic storm of young Solar Cycle 25. "Very bright and active waves of aurora danced with morning twilight," reports John David McKinnon of Alberta, Canada, who photographed the display from Sandhill Crane Marsh:

BLACK AURORAS OVER SCOTLAND: Red. Green. Purple. These are the colours we usually see during any display of auroras. On April 18th, Alan C. Tough of Hopeman, Moray, Scotland saw something else. "Black," he says. In the photo below, "note the dark vertical strip above the green band, which is devoid of any normal auroral colour."

AURORAS ON FIRE: Earth is inside a stream of solar wind blowing as fast as 600 km/s. Last night, the buffeting ignited intense auroras over Alaska. "They were on fire!" says Todd Salat, who photographed the display from the Brooks Range:

SOLAR WIND SPARKS AURORAS: Arriving earlier than expected, a stream of solar wind hit Earth's magnetic field on April 16th, sparking 6 hours (so far) of G1-class geomagnetic storms. In Östersund, Sweden, Robbin Gälliner photographed the storm's green and purple glow:

FLYING TO THE VOLCANO: Iceland's Geldingadalur volcano has turned into an popular tourist attraction---especially since auroras were sighted above the glowing lava. Early this morning, Tuesday, April 6th, Brian Emfinger saw auroras before he even reached the Reykjanes peninsula.
"I was flying high above Greenland en route to the volcano when auroras appeared outside the window," says Emfinger. "I could see them with my unaided eye, and the camera picked them up easily."
There was no special reason for the display. Geomagnetic indices were low and the solar wind was blowing slowly when Emfinger looked out the window. Sometimes auroras just happen around the Arctic Circle. Let's hope they happen again when he reaches Geldingadalur.

AURORAS OVER AN ERUPTING VOLCANO: The last time a volcano erupted on Iceland's Reykjanes peninsula was almost 800 years ago. So consider this a 1-in-800-year shot: "On March 24th, I photographed the Geldingadalur volcano with auroras dancing overhead," reports Christopher Mathews.

AURORAS IN THE USA: A solar wind stream hit Earth's magnetic field on March 20th, igniting a brief but strong G2-class geomagnetic storm. Bright auroras illuminated skies over Canada, then spilled across the border into the USA. "There was an explosion of colour," reports Greg Ash, who took this picture outside Duluth, Minnesota:
