The Moon and Saturn will share the same right ascension, with the Moon passing 1°46' to the north of Saturn. The Moon will be 15 days old.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From São Paulo (click to change), the pair will be visible between 17:58 and 06:09. They will become accessible at around 17:58, when they rise 7° above your eastern horizon, and then reach its highest point in the sky at 00:05, 88° above your north-eastern horizon. They will become inaccessible at around 06:09 when they sink to 8° above your western horizon.
The Moon will be at mag -12.5, and Saturn at mag 0.0, both in the constellation Sagittarius.
The pair will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.
A graph of the angular separation between the Moon and Saturn around the time of closest approach is available here.
The positions of the two objects at the moment of conjunction will be as follows:
