Description

I was very keen to see how the streamer that has calved off from the GRS was developing. The day before the GRS transit was only visible from my location either in the early evening or the morning and in both cases the altitude of the planet was low. For this capture the GRS transit took place when the planet was near the zenith. I was delighted to see that the seeing was excellent and the feed to my monitor looked like a black and white picture for each colour channel. This allowed me to achieve a very good resolution in this South Up image. The amount of detail visible around the red streamer emanating from the GRS is pleasing. As you can see the streamer has moved through the Red Spot Hollow (RSH) and penetrated to the South Tropical Zone (STrZ), when it is dispersing in a longitudinal direction.
Io is upper most in the image and was moving from left to right away from Jupiter. It was thus behind the planet and we are seeing the pro-Jovian Hemisphere. Conversely Europa was moving the opposite direction and was soon to pass in front of the planet and so we are seeing the anti-Jovian Hemisphere.
