Jupiter and 136199 Eris will share the same right ascension, with Jupiter passing 9°56' to the south of 136199 Eris.
From South El Monte , the pair will be visible in the morning sky, becoming accessible around 21:05, when they reach an altitude of 21° above your eastern horizon. They will then reach their highest point in the sky at 02:20, 79° above your southern horizon. They will be lost to dawn twilight around 05:45, 44° above your western horizon.
Jupiter will be at mag -2.9, and 136199 Eris at mag 17.9, both in the constellation Aries.
A graph of the angular separation between Jupiter and 136199 Eris around the time of closest approach is available here.
