Rosh Chodesh Benching Alone

Hi Rabbi,

Does one need to have a Minyan for Rosh Chodesh benching (Birkat HaChodesh) right before Musaf, or can one say it alone?

Shalom,
The Mishna Brura (417,1) explains that the idea of benching Rosh Chodesh on the previous Shabbat is to remind us to observe it. Therefore, there is no need for a minyan and one can do it alone.
With Love of Israel,
Rav Ari Shvat
