Notes
Even more cars. A tinge of twilight on the horizon, increasing noticeably throughout the session. It was a race against the clouds moving in from the southwest. Mostly seemed like the high clouds were either too thin or were dissolving before making it east of my location. Clouds definitely thickened to the west over time. Seems like either the light pollution from headlights or the sunlight decreased the quality of these images. Missing a glove was not pleasant (lost the right one and wore the left backward on my right hand so it was easier to operate the camera). Definitely need a new set of lighter/thinner gloves, and probably a new location away from the highway for observations this late (less cars) and a lower horizon on the 12th.

looking southwest over the Kenai Peninsula at approaching clouds, maybe there were less clouds than i thought
