    So, to continue.  I decided the Moon Sun angle was 90°, because I could only see 50% of the Moon.  However, we mustn't neglect the fact that this situation would also arise between between 18.00 amd 21.00UT on 22Aug2025 when it would be sunrise on 23rd in the Far East when we'd be looking east across the Pacific towards the USA.  I'm coming towards this point of view.  To be continued.  DaveP
