Sequence starts at 22:11 UT with Io as the brighter inner moon and Europa over on the right.
Atmospheric conditions were generally rather poor on this evening and the image quality varies greatly during the course of the imaging run.

Images taken with an ASI120mm camera with either an IR pass (685nm) or Red filter. The difference in filter type causes the GRS to darken when the red filter is used.

Io initially partially occults Europa at 22:20 and its shadow partially eclipses Europa at 22:48. The fall in the light output of Europa is quite obvious even though the conditions were quite poor at the time.
