Q. Kevod Harov Shlit’a. When is the earliest time after an early Maariv after Shekiah that people can say Kiddush Levanah, during winter?
A. On question 3279 we wrote: “Horav Shlomo Miller Shlit’a mentioned once that a minyan that davens early Maariv after the Shekia, could recite Kiddush Levana when in need, even only eighteen minutes after the Shekia, as long as they can clearly see then the moon.
The fact that one can recite Kiddush Levana with a group of people or a minyan and comply with the mitzva of ‘Berov Am Hadras Melech’ or keeping with a mitzva with many, and also avoiding some of forgetting to do it, is most important.” See also Teshuvos Vehanhogos (O.H. 4: 93). and question 3555 in this forum.
