Jovian moons naked eye this morning!

在討論區上看到一段這樣的文字，個人不作評論，而中國古代是有天文學家留意到木星旁有小星運動的。

I went out to get the newspaper this morning and Jupiter was directly overhead. It was 6 AM, a beautiful Colorado morning with temperatures in the fifties telling me that Fall is here. Stopping to look at Jupiter, I noticed how steady the air was and thought that the seeing must be very good because none of the bright stars had any twinkle. Then I saw what appeared to be a bright spike coming out of the west limb of Jupiter. Could it be? Back inside I checked on SB's iPad app, Gas Giants, and yes -- Io and Ganymede are extended off the western limb with Ganymede out the farthest.

This is the first time I've ever "seen" the Jovian moons naked eye.
