G3 Aurora Recorded Sept 27/28 – More G1 Ahead

Northern Lights Now – The late September geomagnetic activity resulting from a large coronal hole has exceeded initial expectations reaching G3 storm levels and helping aurora hunters world-wide capture staggering views. Solar wind speeds have been between 650 and 750 km/s for just over 24 hours now. Periods of high density and negative Bz, and quickly fluctuating Bz during that time pushed KP values above 6.67 for several hours.

Recorded KP values from SWPC in Boulder indicate 7 synoptic periods for G1+, 2 with G3 stroming

The timing worked well for aurora hunters from Northern Europe across Northern North America. Clouds disrupted viewing in the UK and New England, but many locations saw vivid displays of Green, Red and Purple overnight.

Looking ahead – it seems likely that at least G1 storming will continue through at least the next 12 hours or so. SWPC has extended their G1 storm watch an additional 24 hours through Sept 29.

Looking ahead - G1 watch is extended through Sept 29

G3 Aurora lights up the Sky Memorial Day weekend 2017

Northern Lights Now – It may be approaching the quieter part of the Solar cycle, but the Sun isn’t done giving Aurora hunters eye candy yet. A solar storm launched on May 23 from the Sun arrived at Earth with a bang late Saturday. The setup of the storm was great for viewing aurora, the Moon was a waxing crescent, it was the weekend, many of the top viewing spots had clear skies, and the CME was oriented in a nearly perfect angle.

In Vermont, this turned out to be one of the best storms I have personally seen. The KP started rising quickly mid-to-late afternoon. Around Sunset the KP hit 6.33 – high enough that it should be possible to see the aurora dance. By 1:00am it was full on “Pants on” time. I drove to Malletts Bay.

As I arrived, the sky was dancing. Another photographer was just finishing up a half hour time-lapse. Even with some light pollution from Colchester, Montreal, and Plattsburgh, it was easy to see the sky glowing and pillars moving. Lake Champlain was calm so it was possible to see the aurora reflecting off the water.

With the Bz solidly below -15nT, the show would go on for 6+ hours. Like any northern lights, the intensity varied from minute to minute. At times it looked like the show might be over. At other times I felt like the luckiest guy on Earth.

One of those lucky moments was getting to watch a meteor streak and flash through the sky. My camera wasn’t pointed in the right direction (or in an exposure at the moment), but a fellow photographer and friend caught it! Here is Brian Drourr’s photo from the moment it streaked by

What an Epic night!
