Strong G3 Aurora Lights The Sky May 6-8 2016

Northern Lights Now – Geomagnetic storming resulting from a coronal hole high speed stream pushed the alert level to G3 (KP=7) this Mother’s Day weekend treating aurora hunters around the world to a beautiful display. The active period produced one period of G1 storming on May 6, then a much longer and stronger period lasting 21 hours started early on May 8 GMT. Take a look at the 3-hour measured KP graph from the SQPC in Boulder:

Brian Drourr, a Vermont photographer and friend of NLN, was taking this storm in from the Algonquin Radio Observatory in Ontario, Canada, when he captured one of the most iconic images of the active period. That photo, with the ARO in the foreground and stunning green and purple northern lights in the background, is the feature image for this post, and we thank Brian for allowing us to share it with you. You can find more information about Brian and his photos on his Facebook page

The Visible Infrared Imager Radiometer Suite (VIIRS) is a satellite that is capable of capturing the Aurora as it dances from space. This image shows the Mother’s day Northern Lights dancing over Central Canada and the upper midwest. If you look closely (click on the image to zoom) you will be able to see the Fort Macmurry fires in Alberta along the Saskatchewan boarder:

Here are some more great photos that came in from Twitter over the last couple days:

Northern Lights Now – Aurora hunters from Europe to Central North America were treated to aurora as the result of a G3 Geomagnetic storm On March 6-7 2016. Images of aurora filled Twitter, as photographers who stay up late snapping pictures of the night sky shared their success stories. In addition to the photos, several tweeters shared their time lapse photography. NLN has compiled some of the best time lapse in this post. Enjoy!

Astronaut Tim Peake kicked off the evening’s Aurora time-lapse with this “Aurora photobomb” from the International Space Station:

Mac The Hat posted this tweet from the Beauly Firth near North Kessock in the highland of Scotland. In case you were wondering, a firth is a estuary or inlet from the sea:

In N. Ireland, Daragh McDonough (@DaraghDonegal) posted a realtime northern lights capture from a Canon6D from Donegal on the Northwest Coast:

In Maine, the aurora lasted long enough to put on a nice show at Sugarloaf mountain:

Sam Cornwell (@Samcornwell) Shared this wonderful Youtube video he created from images taken in Hawick on the Scottish Borders of the March 2016 storm:

For Hargi (@hargi_) the clouds added texture to the northern lights making a very interesting and lovely time lapse.

Thank you to all he intrepid aurora hunters who brave the cold and dark to share these images with the rest of the world!

Happy Hunting

Coronal Hole Delivers G1 and G2 Aurora on 2/16 and 2/17

Northern Lights Now – The expected high speed solar wind that prompted a G1 geomagnetic watch for February 17 arrived early, but delivered G1 and G2 storming conditions. The wind was faster moving than expected, clocking in around 670 km/s. The fast wind combined with periods of Bz south was enough to excite Earth’s geomagnetic fields. At the time of this blog post, there were 18 hours of continuous G1 and G2 – KP greater than 4.67 and 5.67 respectively – storming recorded, followed by another quick burst. Here is a graph showing the official readings from SWPC Boulder:

SWPC Boulder reports 7 periods, 21 hours, of G1 and G2 storming
SWPC Boulder reports 7 periods, 21 hours, of G1 and G2 storming

While this was a fairly strong aurora storm, there were not many aurora reports. Most of the prime viewing locations were clouded in. An large storm system across Iceland and the British Isles, general overcast across much of Scandinavia, and an East coast ice and snow storm prevented the viewers in the prime locations from experiencing this show. However, aurora hunters in some locations were able to capture the show:

New Zealand was treated to a brief period of lights just before sunrise as the storm started. Both Paul Le Comte and Ian Griffin got out of bed to snap pictures near Dunedin:

In Tasmania, @SussanSays saw the pinks and greens poke through what was forecast to be cloudy skies, and shared it in this Tweet

Eva Olsen captured greens with a hint of red/pink in Lapporten, Northern Sweeden:

Aurora hunter Darlene Tanner recorded the tail end of the storm from Alberta:

It’s possible storming could continue over the next 12-24 hours as disturbances travel along the fast wind stream, but decreases in density and wind speed indicate it’s likely this storm is now over.

Happy Hunting!
