Ganymede eclipses and occults Europa
This image shows a mutual event involving several of Jupiter's moons. In this event, Ganymede totally eclipses Europa and then follows with a grazing occultation. Callisto is at left, and is much darker than the other moons. This time lapse composite image is composed of 7 frames that were acquired over 1h7m elapsed time. The exact time of each individual frame is below (Universal Time):
10:00:36
10:11:22
10:28:22
10:37:46
10:47:58
10:57:27
11:07:27
I also captured the entire event in 30s intervals and posted that result to YouTube:
Each of the component images of the time lapse is the result of an individual 30s video capture, in which 500 frames are stacked for each image. The images were acquired from San Diego, CA, using a C9.25 Edge HD telescope, ASI183mm camera, 1.4x barlow lens, and 610nm filter. Each frame of the video is aligned on Ganymede, and one can appreciate the different relative motion of the other moons at this moment, in addition to the eclipse and occultation of Europa, and also the striking albedo difference of Callisto.
