Mercury and Uranus will share the same right ascension, with Mercury passing 35' to the north of Uranus.
From South El Monte however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 17° from it.
Mercury will be at mag -0.8, and Uranus at mag 5.6, both in the constellation Leo.
The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible through a pair of binoculars.
A graph of the angular separation between Mercury and Uranus 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 |
| Mercury | 10h55m00s | 8°17'N | Leo | -0.8 | 6"5 |
| Uranus | 10h55m00s | 7°41'N | Leo | 5.6 | 3"6 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 17° from the Sun, which is in Virgo at this time of year.

Warning
Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
