I have bagged a good observation of each of these events, except for Callisto where i am missing an occultation disappearance, a shadow egress and a concurrent moon and shadow transit. Because of Callisto’s wide orbit these only occur approximately every 6.5. when the orbital plan lines up with Earth. I have to be patient till some time in 2020/21, I think before I can complete all of these observations.

That reminds me Steve to check for the next Ganymede transit even the shadow transit..always enjoy that one ..see if I can resolve a disk next time..some say the've seen features visually on it.
