Jupiter last night showing the great red spot and the transition of its moon Io.

Obviously it's very low in the sky and the seeing was none too good, both affecting the image quality.  But it seems the GRS has not unravelled further.

Must be quite a challenge to get the planets at the moment being so low in the sky.  I seem to have read somewhere that the GRS is smaller than it was and not just because of the recent unravelling event.  Is it my imagination, but it does indeed look smaller to me?

Well done for getting what you have.

Yes, that'll be Io's shadow.  The question is where is Io itself?  Camouflaged against Jupiter I think.

Very good Mark
The spot is quite clear.

Swapped telescopes for armchair.

Good catch Mark. According to WinJupos ephemerides Io should be just about 0.5 cm (on your image:) to the right of the shadow. I think its just above the dark band making the light band a little darker.

Thanks Mark ~ good to see a planet featured.
