No caption is necessary Katy! This is just great. I've seen the aurora borealis before, but never so clear as you see it in Alaska!

No they don't move as fast as this gif suggests. This is a series of 15 second exposures, so each frame is 15 seconds apart.

However... that said, there is quite a bit of movement in each single 15 second exposure, so each photo has blurred motion. Very difficult to really 'capture' any sharp edges, because they are moving faster than a 15 second frame can capture.

So happy you took a look Betsy, thank you!

Awesome. Love the Series. What an aurora year you have had!
Katy: Write me and tell me if they move as fast as the video suggests.

I've lived in Alaska since 1969. I love this wild land. The extremes of the far north shape and affect every living thing. Extremes of weather, elevation, daylight hours, isolation, flora and fauna, nothing in Nature is insignificant.I have a Davis Vantage Pro weather station, uploading to Wunderground, (Turks on the Tundra) the National Weather Service, the Citizen Weather Observation Program and MADIS (Meteorological Assimilation Data Ingest System).
