Jupiter GRS July 23rd 2012

[Quark (Trevor)]

Hi All,


Imaged Jupiter this morning, funnily enough my best RGB was the first which was with Jupiter the lowest for this session at 25 degrees alt.
Have attached 1 RGB & 807nm IR data set along with an animation of all IR data covering just under 1 hr of rotation.



The GRS remains quite pale compared to oval BA and the colour of the SEB on the preceding side of the GRS remains very distinctive, a dark reddish brown. The reddish band of colour in the EZ continues to be relatively prominent while the NEB remains very disturbed. There is considerable detail in the EZ & NEB resolved in the 807nm IR data.

Thanks for looking.


Regards
Trevor

very nice Trevor. regards Ray

Thanks Derek & Ray but I have had an over sixties moment and labeled all of this data with the wrong UTC date. Have just spent the last hour sending out the corrected data with date & CM's

Trevor,
I always look forward to seeing your work, I am looking forward to making another attempt at Jupiter soon. You certainly set the bar high though.

That oval BA reminds me of the Red Spot Jr of 06 (?)

Thanks very much Julie, look forward to seeing your efforts. This and the following apparitions of Jupiter will be our worst for some time with Jup being a relatively low alt target,but then it will head back our way. I tell the Northern Hemisphere imagers that it is only on lone.

Your are spot on Mike, the official designation for this oval is BA. it has been known for many years but back in 2006 when it first turned red it was also known as Red Junior. Over recent years there have been 3 red spots of note on Jupiter, the GRS, Oval BA and the LRS in the NNTrZ. Astronomers tend not to be very imaginative with naming such things, the LRS being the little red spot.

GRS looks very pale. Nice work Trevor
