Jupiter and Uranus at Opposition

Object: Planets

Site: Front Yard

Seeing: 4

Transparency: Above Average

Type: Solar System

Size: 9″07″

Magnitude: -2.79

Constellation: Pisces

Magnification: 10x

FOV: 4.8 Degrees

Observing Time: 11:00pm – 11:15pm

Notes: Observed Jupiter and Uranus, one night before both of their oppositions.  Jupiter shines at magnitude -2.79, with a diameter almost 9′ wide! This is one of those times that I wish that I had a telescope…only then would I be able to look at the surface of the gas giant itself, and pick out its details. Presumably they should be much larger and better defined, because of Jupiter’s large disk during this opposition.  Europa and Io to the left, Ganymede and Callisto wider-spaced to the right.  Uranus shines at magnitude 5.73, to the northwest of Jupiter. First impressions: almost as dim as the background stars, but not creamy white like Jupiter– it has a blue-green dark hue to it.  29 PSC and 27 PSC to the south of Jupiter.  This is the first time I’ve seen two planets in the same FOV. Each being close to their opposition makes tonight extra special.
