An impressive display of auroras dazzled onlookers in the northern latitudes overnight.
The show was visible in much of Minnesota in the predawn hours today. I spoke with storm chaser and photographer Doug Kiesling today about the show last night. Doug captured some remarkable photos and video near St. Cloud overnight, including this image of a green aurora and a meteor fireball.
A so called ‘G-class’ solar storm is buffeting earth. Astronomy watchers at spaceweather.com describe the impact, and the prospects for more auroras tonight.
CME IMPACT, GEOMAGNETIC STORM: An interplanetary shock wave, possibly the leading edge of a CME, hit Earth’s magnetic field on October 8th at approximately 2015 UT (1:15 pm PDT). The impact sparked a G1-classgeomagnetic storm (in progress) and bright auroras around the Arctic Circle.
Earth is passing through the wake of the CME where a region of high-speed solar wind continues to buffet our planet’s magnetic field. NOAA forecasters, who suspect that a second CME might arrive on Oct. 9th, estimate a 65% chance of polar geomagnetic storms during the next 24 hours. High-latitude sky watchers should remain alert for auroras.
The auroras were visible over much of the northern hemisphere overnight. You can see more great photos at spaceweather.com.
There is a chance for another show tonight. Here’s the discussion from NOAA’s Space Weather Center.
2013-10-09 01:05 UTC Minor Geomagnetic Storm Occurring
A shock in the solar wind passed earth late on October 8 (UTC) bringing unanticipated G1 (Minor) Geomagnetic Storm activity. The brunt of the disturbance is expected through the early hours of October 9 (UTC), then followed by a second pulse later on October 9. Watch for updates here.
Best viewing is away from city lights in the northern sky. Keep you eyes in the sky!
