The Great Red Spot is highly sheared on the western edge.

CM3: 303.40°

CLat: -3.20°

Description

I wasn't expecting to image within the next week. However, I found Jupiter shining through a very thin cloud layer, so I hastily set up the C8 in a race against the clouds that were predicted to arrive at any moment. This was the first light of my new ZWO RGB filters, which I find to be much better than the Orion filters I was previously using with the this telescope.

Notes:

Io and its shadow is transiting the North Equatorial Belt.
White Oval Z is directly north of the Great Red Spot.
The Equatorial Zone is still orange. The southern edge appears to be finally losing its white color.
The South Equatorial Belt appears to be split by a white zone. The southern edge of the belt appears more gray than brown.
The Great Red Spot has a large flake on its western edge.
Another cloud flaked off the GRS a few days earlier is to the east of the storm.
