At the April 4, 2015 lunar eclipse, Earth’s dark umbral shadow barely engulfed the moon for about 5 minutes. At maximum, the moon was only 2 arcseconds within Earth’s shadow, according to some estimates. That’s in contrast to an average of about 1800-1900 arcseconds for the diameter of the moon itself. So you can see that the moon was barely within the shadow! EarthSky friends captured both the partial and the total eclipse.
