Northern Lights Now – It has been such a treat attending the Space Weather Workshop in Boulder Colorado. It is exciting to watch the ideas and collaboration arise as this wonderful community of academic, government, commercial, and enthusiast space weather stakeholders collaborate.

As I’ve been talking with people and explaining NLN, I’ve realized that I need to have a simple central place to access some of the more scicom-ready data visualizations, stories, videos, and just plain cool examples as a jumping off point. This blog entry is that.

Blog post describing our successful aurora hunt in the 2015 St. Patrick’s day G4 Geomagnetic storm and Aurora.

Generally the more bars, and the higher the bars the more likely it is that aurora will be visible. Each bar represents the time that a solar wind parameter has consecutively exceeded a threshold.

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.

Wendy T shared this great set of 4 images

Casey Grimley captured some pinks and the coveted fishbone aurora in Ogden Valley

And Jeff Wallace shared some spectacular full sky Gree swirling aurora

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

We love that you share your photos with us on Twitter and on Facebook. Thank you for helping with out mission to help as many people see the aurora borealis as possible.

Happy Hunting

G2 Aurora Recorded – G3 possible Sept 27

Northern Lights Now – Quick Update: The expected coronal hole high speed stream arrived with a bang. KP levels have reached G2 and the forecast calls for KP=7.33 in the next hour.

Aurora reports have been streaming in from Northern Europe and Iceland over the last couple hours. As the Sun sets across Eastern North America, expect additional reports to come in from the Northern United States and Canada.

KP 7.33 is expected in the next hour.
KP 7.33 is expected in the next hour.

The Wing-KP short term forecast is calling for KP levels to reach G3 levels in the next hour.
