Fortunately, the local weather was not as bad as predicted, but we still had to deal with passing clouds and high altitude haze. I set my gear up to take one picture every minute throughout the duration of the eclipse and fortunately the Sun was in clear sky during the maximum coverage (about 89%). This is the single frame taken near the moment of central eclipse, showing the moon’s northern hemisphere silhouetted against the Sun.

Although we did not get the total eclipse, the effect was still quite surreal. As the eclipse deepened the ambient illumination softened and turned gray. The effect was strengthened by the partly cloudy skies that scattered the dimming sunlight. Quite beautiful in its own way.
