Hello,

I've been seeing this big white ball of light at night. Today I saw
it like for the 5th or 20th time and decided it was time to figure
out what it was.

I heard about some kind of comet passing by but haven't seen it.

I figured as much it's either jupiter or a plane.

But in this case I was kinda amazed that I could also see 4 moons.

On closer inspection of one of the pictures it seems that maybe some
other tinier moons are also visible at the "bottom" of jupiter ?!?

I am not sure if these are real moons or jpeg artifacts.

I think the position of jupiter, earth and the sun was such that
jupiter and moons received maximum light from the sun and reflected
back to earth/netherlands pretty good so it's a little bit special
maybe not too special, but special enough to warrent a few fotos and
some videos.

I know my camera (cannon powershot hs sx 50) also has "RAW" mode...
maybe tomorrow I try again and avoid jpec compression to avoid any
jpeg artificats.

Let me know your thoughts on "little ones" visible or not on that
picture.

Here are the links:

I think now jupiter/earth/sun moved such that it's now less bright
so won't continue the raw experiment for now, but maybe tomorrow.

Anyway enjoy the pictures. The one with the little ones visible too
was taking a bit earlier than the other one... the other one kinda
looks nice too.

I am quite amazed/kinda surprised that it's so visible and vieweable
with a consumer camera =D

I think I have seen it before with my camera but not sure ! =D

At least now it's documented ! =D

Bye, Skybuck =D

The four biggest/brightest moons of Jupiter are known as "the Galilean
moons" discovered by *Galileo Galilei* in 1610. These are what you were
seeing!

Looking at the chart at https://en.wikipedia.org/wiki/Jupiter , the four
of them rotate around Jupiter fairly fast (between 1.77 and 16.69 days),
so it would seem that one of the big four may have been in front of or
behind Jupiter when you could only see three of them!
