I’m gonna leave you guys with a cheat sheet courtesy of @YourBasicMaths and embellished by me. If you time your pic snap right, you can capture these times and verify you are in sync.
Only thing for you to do is figure your local time at those UTC times listed so you will know when to make the observation.
Pics are not required. I just use them for my own personal record.
(16 minute variance of the game time listed is acceptable)
