G'day all,

 

For a mild jet stream (15 m/s and slowing), seeing was pretty abysmal for this evening's GRS transit. There was a near-constant, very high-frequency component to the turbulence that prevented sharpening on the screen. I couldn't get the leading edge of Jupiter's disk sharp at all, and Io barely registered, flickering brightly every once-in-a-while. Thankfully, there was no fast tilt component, so I had no trouble keeping the disk on the screen…

There's most certainly some blue getting churned up upstream of the GRS…

 

Cheers,

BQ

Nice one BQ!

 

I also noticed a blue feature in the wake of the GRS when capturing some data last night ... it was so prominent that it was clear even in the noisy raw frames. Processing the data now ...
