[ValleyNature] Jupiter Observations

[Sherman Williams]

Jupiter is becoming prominent in the late evening sky  (the bright  
"star" above the southeast horizon).  Aug 5 and 6 Jupiter is the  
bright starlike object near the Full Moon.   Recently it has been  
moving past a star that is about the same brightness as one of  
Jupiter's 4 Galilean moons (45 Capricorni). The position of this star  
has been giving the appearance of an extra Galilean moon as Jupiter  
moves past it.  Altough this  at minimum has been a small telescope  
event, you may be interested in the sketches of two recent  
observations and what it represents.

In all I managed 3 different observations of Jupiter between Aug 1  
and Aug 5 showing its "5th moon", 45 Cap.  Missed the occultation  
event (when Jupiter moved in front of the star) but since then  
managed these two interesting views recorded in sketches I made  
linked from here:
