Greetings from San Carlos de Bariloche, Argentina. For the next 3 weeks I will be posting with the perspective of viewing the sky from between around 42o-48o south latitude, and then from the equator while in Quito Ecuador.
On the evening of January 13th both planets, Mars (23o) and Uranus (23o), will be at about the same heliocentric longitude or at heliocentric conjunction. While they may share nearly identical heliocentric longitude coordinates they do not have the same right ascension with Uranus about 2 hours of R.A. west from Mars. Both Mars and Uranus are visible over the southwestern horizon a couple of hours after sunset, although it may prove to be difficult to see Uranus with an apparent magnitude of nearly 6.0.
