I shot it overnight.. From around 11 pm to about 5 am. Memory says it was a timelapse of 5 frames a minute ... about 1800 images. Aurora happen year round. In Yukon we only get to see them from September through April. After that there is too much daylight. If you are interested in the lights; here is one of my favorite websites... www.swpc.noaa.gov/products/aurora-30-minute-forecast Where are you from?
