SCHRÖDINGER’S CME: Yesterday, June 26th, a bright CME billowed away from the sun’s southern hemisphere. The strange thing is, analysts aren’t certain which side of the sun it came from. Some clues suggest far side, others Earthside. If it is an Earthside event, it could reach us late on June 28th or June 29th.

Potential Impacts: Satellite systems may experience significant charging resulting in increased risk to satellite systems.
MIDSUMMER AURORAS: Normally, summer is not a good time of year to see Northern Lights. Nights are short and barely dark enough to reveal the delicate glow of geomagnetic activity. Yet, on June 26th, there it was:  “Wow, talk about surprises!” says photographer Harlan Thomas of Calgary, Alberta. “I went out to shoot Comet C/2017 K2 Panstarrs and the Moon-Venus conjunction when these auroras appeared. The display lasted all of 5 minutes, and what a 5 min show it was as the aurora became naked eye with beautiful pillars.”What caused the display? A co-rotating interaction region (CIR) hit Earth. CIRs are transition zones between slow- and fast-moving streams of solar wind. They contain strong magnetic fields and shock waves that do a good job sparking auroras–even during summer. The impact of this CIR caused a G1-class geomagnetic storm that lasted 6 hours. |
