This morning around 4:30am, I looked out from the window, I saw Jupiter hanging outside.
It was sinking rather low in the sky, and it was quite misty there. I pulled out my Canon 10x30 IS to confirm, and I couldn't see the satellites quite clearly, but then I moved my head a little bit, they were there. I guess the window frame was killing the resolution, so moving slightly off to avoid the thickest part helped.
It reminded me the planet season comes again! I guess the observation time would be like 2:00am to 3:00am these days. Time to give up some sleep.
