Aurora can be faint, so much so that it is only detectable by long-exposures. In this
timelapse, normal light pollution at left gives way to a reddish Aurora, over the beautiful
Boreal forest in northern Canada.
Time-lapse length (30 fps):
11 seconds.
…which strobe, creep, and flow in the night sky. The continuation of another clip. High Cirrus,
highlighted in red by normal light pollution from one of the most northern towns of Alberta,
stand against the bright green of the northern lights. It is likely coincidence that makes the
clouds and Aurora seem connected in some ways at parts of the sky. There is no ground horizon
shown exempt for a small outline of trees in the bottom-right of the frame.
Time-lapse length (30 fps):
7 seconds and 27 frames.
… which strobe, creep, and flow in the night sky. Comprised of charged particles, the lights are
playing on the magnetism of the Earth. Mid-level stratus clouds are lit by town lights far away.
Long exposures and low ‘coma’ (comatic aberration).

Flowing in the night sky. A clip of greener Northern Lights typical of northern
latitudes during a solar maximum. Long exposures and low ‘coma’ (comatic aberration). Temps:
Sub-zero (F) at ground-level.
Time-lapse length (30 fps):
25 seconds and 23 frames.
The beautiful Northern Lights, slow and lingering in the sky due to a little bit weaker solar
activity from prior discharges of the sun. Peaceful over the Boreal forest in northern
Canada.
Time-lapse length (30 fps):
12 seconds.
The view over sub-arctic woods at night. One of the last areas this far north with any
significant light pollution (man-made light that has a significant impact on the darkness of
the night), the Northern Lights are observable in the distant thermosphere, around 65 miles
above the Earth. This clip contains the lowest amount of transforming aurora in the entire
collection.
Time-lapse length (30 fps):
7 seconds and 65 frames.
A towering complex of clouds at sunrise, with the sun outside the frame. The point of view is
angled steeply upward and southerly. Where the sun glows in amber and gold on the clouds exposed
to its light, both delicate outer edges of denser towering clouds and nebulous areas from later
in convection are brightly illuminated. Almost certain is the probability these clouds will
produce rain later in the day.
Time-lapse length (30 fps):
11 seconds and 24 frames.
