Chart for Mercury apparent position (for Chicago but applicable for SLC) for March and April. - Kurt http://www.curtrenz.com/mercury01.html P.S. - Here's the local horizon coordinates for Mercury from SLC for the next week at 7pm and near sunset at 8pm. (Alt = 90-Zenith Dist). Jupiter will set just before Mercury at about 1 degree WS of Mercury and 5 to 6 degs below in az from Mercury. So a good finding option is to zero in on Jupiter with your binoculars and then swing up and slight to the north in az until you roll over Mercury. Using your planetarium software to chart Mercury at the west horizon at around 8pm between 3-20 and 4-7 with day connection lines gives a useful graphic. Mercury reaches maximum elongation on 2011 Mar 23 7:10pm at 18.6 East with a magnitude of -0.2.
