Get yourself out and have a look towards the west after sunset tomorrow evening (8th March).
The Moon will appear as a very slender crescent low over the western horizon.
So make sure that you have a good low view in that direction.
The image below shows the appearance of The Moon at about 18:15 (UT).
So get yourself out and see if you can spot it.
Mercury is to the right and a bit lower than the slender crescent Moon so will be even more difficult to spot so low down.
But hey, give them both a go.
