GRS Fling

Hi all,
Due to 12V cord failure I wasn't able to image on the night I wanted too. I made a temporary cord which seem to work just fine for now.

Any way here is the image of Jupiter and Io from the 25-5-19 12-23 UT in average seeing conditions. Jupiter's altitude for my location was 53 and Jupiter's current size is 45.5".
I have enlarged the image a bit more than normal so you can see the material shearing off the GRS. I thought I will still post the image in case people are following the GRS developments at the moment.

Cheers

Equipment:
C11 Edge
ASI224mc
ADC

Nice capture, Troy

The GRS is really active this year...

Thanks Dunk,
Not sure if the GRS is shrinking at a faster rate with all this activity but it gives us good opportunity to image the event either way.

That's an excellent image with a lot of detail evident and good colour, can easily see what is happening to the Red Spot with the cloud shearing off into the surrounding jetstream. Has been fascinating to see the changes over the past few weeks and wanting to see more higher resolution images from the experienced planetary imagers, please.

Thanks for your encouragement Jeff and hopefully on my next days off the conditions and hardware cooperate.

Great detail with the GRS, it is really very small now, a little over an Earth diameter. It seems to be vomiting itself away.

Sky and Telescope have an article about the GRS shrinking.

Jupiter's South Equatorial Belt appears to be pulling material from the Great Red Spot in an event that's visible in small scopes.
