ZD, the big question is what to do about Kiddush Levana on the Moon. When is Shabbat?
BTW, when Rav Shlomo Zalman Auerbach’s son-in-law came back from the US RSZ excitedly asked if he had been in a skyscraper. He had a theory that if one twin was born on the ground floor and another on the top floor around sunset the one born first might be bar mitzva second.
