I forgot to mention that if the launch occurs at the start of the launch period, 3 July, 0 h UTC, the orbit will offer at least morning visibility for northern hemisphere. Those north of the mid-northern latitudes will have all-night evening and morning visibility - all-night visibility. At my location, about 44 N and 80 W, I have a pass in evening twilight, on rev one. Unfortunately, I expect clouds for the next few days. I have not evaluated southern hemisphere visibility, nor the effects of a late launch. Happy hunting!
