You can see that the impact site (near South Pole, south is up) has changed quite a bit since the impact. There appears to be a circle in the middle that the rest of the impact is bending around.
GRS is near limb and the storm near it appears to have intensified.
Ganymede is the moon to the right of Jupiter and Europa can barely be seen "on top" of Jupiter (you can see it's shadow easily and Europa is to the right).
