Interesting exercise Bob. I shall try next year as Saturn’s opposition approaches.
This reminds me of my little project to bag a detailed observation of each of the 11 events for the Jovian moons; occultation - disappearance & reappearance, eclipse - disappearance & reappearance, transit - ingress, transit & egress, shadow - ingress, transit and egress and a concurrent moon and shadow transit.
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.
