Down at lower latitudes, where you are further away from the aurora a bright moon can really wash out the view. No problems with that here as the moon is rising under a nice arc...

Lady Aurora and The Sun do battle once again as twilight approaches...meanwhile the Milky Way stretches out overhead...
These light/dark transitions with aurora are some of my favorite scenes to capture in this hobby. Always challenging as you react to the changing light conditions...

Winglets or Wingtip devices are usually intended to improve the efficiency of fixed-wing aircraft. There are several types of wing tip devices, and although they function in different manners, the intended effect is always to reduce the aircraft's drag by partial recovery of the tip vortex energy. Wingtip devices can also improve aircraft handling characteristics and enhance safety for following aircraft. Such devices increase the effective aspect ratio of a wing without materially increasing the wingspan. An extension of span would lower lift-induced drag, but would increase parasitic drag and would require boosting the strength and weight of the wing. At some point, there is no net benefit from further increased span. There may also be operational considerations that limit the allowable wingspan (e.g., available width at airport gates).
Wingtip devices increase the lift generated at the wingtip (by smoothing the airflow across the upper wing near the tip) and reduce the lift-induced drag caused by wingtip vortices, improving lift-to-drag ratio. This increases fuel efficiency in powered aircraft and increases cross-country speed in gliders, in both cases increasing range. U.S. Air Force studies indicate that a given improvement in fuel efficiency correlates directly with the causal increase in the aircraft's lift-to-drag ratio (Wikipedia).
It was definitely a crisp, cold night in northern Minnesota...parked as you see here for much of the night, occasionally venturing out into the -2F temperatures for shots as the aurora played across the horizon.
