Mike and Paul,

Thank you for the compliments on my Jupiter observation. It is not easy to render the subtle detail visible over Jupiter, as you are well aware of. This planet exhibits delicate detail, many times at the limit of visibility.

The eleven (11) minute limitation refers to the fact that Jupiter rotates very quickly (Equator rotates in a period of 9 hours 55 minutes 30 seconds at a rotation velocity of 28,148 miles per second (45,300 km/sec)). This, unfortunately, does not give the observer much time to record all features visible at leisure (say compared to Mars). If the observer records the major features visible then adds the detail afterwards (starting towards the preceding limb before the features disappear) then one can obtain an accurate record of what was visible.

The best of luck in your own observation of Jupiter.
