Q. In our small weekday minyan we have a problem getting someone to blow the Shofar daily…
If we could not find someone in the morning can we blow by mincha?
A. When the Tzibur did not blow the Shofar after Shacharis, Igrois Moshe (O.H. 4: 21: 5) rules they can blow after Mincha, since the Remoh (O.H. 581: 1) writes that there are places where the custom is to blow in the evening every day (See also Nitei Gavriel- Rosh Hashono p.55).
