Three moons of Jupiter

I woke up a bit early today - actually, six-thirty in the morning is not early - and went out of the house to enjoy the cool morning air. It's second nature for me to glance up to look at the stars, moon and what-not, and I saw what I believed to be the planet, Jupiter, in the still-dark sky. So I went for my camera and snapped a few pictures for confirmation. Yup, I was correct. The bright spot in the sky was indeed the largest planet in our solar system. Plus, three of the four Galilean moons could be seen clearly. Couldn't view the fourth moon: I think it was either transiting in front of the planet or occulted behind it.
