In the evening of 12 May 2021 at 8:41pm, the waxing Moon was near Venus low in the western sky. Clear conditions allowed a fine binocular view. Without them, I would not have seen the Moon’s very thin crescent.
If the sky is clear the evening of 13 May, look again for the Moon in the west. It will be to the left of Mercury this time. Not quite as close as it was to Venus. Binoculars will help. The Moon will be illuminated 4.34% and easier to find.
