To give you an accurate translation of "good noon," you need to specify which Manobo language you're interested in.
For example, if you're looking for the phrase in Higaonon Manobo, it would be "Magandang udto" (pronounced "ma-gan-dang oo-dto").
Please provide me with the specific Manobo language you need the translation for, and I can give you a more accurate answer.
