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.
