The Moon and Mercury will share the same right ascension, with the Moon passing 8°15' to the north of Mercury. The Moon will be 29 days old.
From Cambridge however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 14° from it.
The Moon will be at mag -8.2, and Mercury at mag 2.8, both in the constellation Taurus.
A graph of the angular separation between the Moon and Mercury around the time of closest approach is available here.
The positions of the two objects at the moment of conjunction will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| The Moon | 05h48m00s | 27°02'N | Taurus | -8.2 | 33'05"4 |
| Mercury | 05h48m00s | 18°46'N | Taurus | 2.8 | 10"7 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 13° from the Sun, which is in Gemini at this time of year.
