G2 Aurora to Start September 2016

Northern Lights Now – A widespread aurora display delighted viewers across northern Europe and North America on September 1st and 2nd. Kp values, a global measure of aurora activity, reached G2 storm levels. Northern lights were visible in Denmark, Maine, New Hampshire, Wisconsin, and across Canada.

Here are some highlights from Twitter, check back tomorrow for a more detailed storm recap:

August 2nd & 3rd Solar Storm Live Blog

Share Button

Northern Lights Now – SWPC has posted a G2 storm watch for August 2nd and a G1 storm watch for August 3rd. NLN will keep a live blog of the storm as it unfolds here.

Update 8/4 2:30 UTC (10:30pm EST)

A quick recap: The big winners for aurora photography in this storm were the Northern states west of the Great Lakes and Canada, New Zealand and Tasmania. Denmark was also in the sweet spot at the very beginning of the storm when the initial CME arrived. There were a couple pictures of faint pillars in ME, NH and VT as well.

Solar wind never quite reached the high levels expected in the prediction. The helps explain why the storming started a little later than predicted also – if the wind is moving slower, it takes longer to travel from the Sun to Earth. In the end there were four periods of G1 storming recorded.

Thanks for following along for this storm!

This solar storm is done, in total 4 periods of G1, and 4 periods of KP=4. 24 hours total.

Update 8/3 16:30 UTC (12:30pm EST)

The storm seem be dying down. Solar wind speeds have picked up, but they did not reach the predicted 600+ km/s. Here’s a create timelapse video from overnight from Robert Snache (@spirithands)

Update 8/3 11:00 UTC (7:00am EST)

So many wonderful pictures overnight. There were 3 periods of G1 recorded, and it appears there is a 4th happening now. There is an outside chance that the current period will reach G2. Here are a couple tweet with aurora pictures the we’ve seen overnight:

Update 8/3 04:45 UTC (12:45am EST)

Starting about an hour ago, Bz dipped back south. Bt is still very strong, so this may be enough to produce some more pillars in the mid-latitudes. Aurora hunters will still probably need long exposures to get a good view. KP=5.33 (G1) in 20 minutes. Here’s a look at the boulder KP 3-hour averages so far – notice that storming didn’t technically reach G2 levels during the last substorm:

Update 8/2 23:00 UTC (7:00pm EST)

G2 storming is now predicted by the Wing-KP model. KP=6 shortly! This is almost exactly when the initial forecasts indicated we might see G2 storming. The strong solar wind hasn’t really picked up yet – wind speeds have only just touched 450 km/s.

Wing-KP shows KP=6 soon on August 2

Bz shifted to the north, so NLN is expecting this storm to be short lived. Good luck. Hopefully there will be more later tonight

Update 8/2 22:30 UTC (6:30pm EST)

First aurora picture of the night! This tweet shows a photo from Denmark by Twitter follower @ADphotography24

Update 8/2 21:45 UTC (5:45pm EST)

Around 8:00am UTC Bz made a decisive shift to the south. This should be good for aurora hunters and we expect to see some pictures coming in soon. We also expect the wing-KP models to reflect this aurora within the next 2-3 hrs.

Update 8/2 06:30 UPC (2:30am EST)

The first hints of the expected solar storm from the filament eruption appear to be arriving. Solar wind, density and Bt/Bz all reflected the shocks impact. The shock was weaker than expected, but also a little earlier than expected. We’re not really expecting any aurora yet, still plenty of hours ahead for a show.

Initial CME arrives around 04:00 UTC on August 2

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:
