Jupiter Viewing, 2020

Post by Christopher K. »

Jupiter's opposition in 2020 occurs during the 3am hour on 14 July. Accordingly, the Jovian Opposition viewing at HRPO will be...
*Monday 13 July from 9:45pm to 11:45pm CDT.

Jupiter will be in the constellation Sagittarius and will be seventeen degrees above the horizon at the beginning of the event. During this time all four Galilean moons (Io, Europa, Ganymede, Callisto) will be visible. Io and Ganymede will actually switch positions right before closing time!

Pallas and Saturn will also be in the night sky. The event will have no admission fee and will be for all ages.

If you haven't noticed Jupiter in the night sky, you're missing out. A binocular held very steady will reveal four of Jupiter's numerous moons. These four Galileans are the only four visible from Earth with amateur equipment.

Below are the times during upcoming selected morning during which Jupiter reaches twenty degrees altitude in the southeast, and how much time in hours and minutes (in brackets) Jupiter is visible during the morning before twilight...
Monday 6 April = 4:36am [0:46]
Thursday 9 April = 4:25am [0:56]
Sunday 12 April = 4:14am [1:02]
Wednesday 15 April = 4:04am [1:09]
Saturday 18 April = 3:53am [1:16]
