Double Transit Sketch

Last monday night,caught the double transit on Jupiter I've drawn a sketch and the moon shadows were very sharp like holes drilled though the planet.

Thomas,

Thank you for posting your excellent observation of Jupiter showing the satellite shadows. You have recorded the appearance of the satellite shadow very well. The Great Red Spot (GRS) region is well recorded as well. Please keep up the good work. You will notice that you will be recording more detail as your eye gets accustomed to faint structures over the disk of Jupiter.
