Adoration and exposition

In Paul Turner's Blog by Paul Turner

Q: People at my Church want to have the tabernacle open for them to pray without exposing the Eucharist on the altar. Is this ok to do?
A: No, there is no provision for that. Adoration may take place privately before the closed tabernacle at any time, or publicly during the liturgical exposition of the Blessed Sacrament in a ciborium or a monstrance.
