The above sketch is mirror-reversed due to the use of a star diagonal. North is up. Preceeding is to the left. The dark spot to the lower left (southwest) is a new impact scar on Jupiter. The small, dark, impact scar was spotted as soon as I looked into the eyepiece and focused the telescope at 218x.
Anthony Wesley, an amateur astronomer in Australia, was the first person to discover this impact scar on the 19th of July. Thanks to the Internet, I heard about the dark spot shortly thereafter.
Considerable fine detail was visible within the two major belts, but I would have had to up the magnification a bit (and taken more time) in order to sketch it. Meanwhile, Jupiter's rapid rotation would have taken the impact scar closer to the planet's preceeding limb and shortly thereafter onto the far side of the planet.
