Hello again

here is a drawing of Jupiter from Saturday afternoon.

I set up the scope and left it to cool while I searched for Jupiter with my 10x50 binoculars, It took about 30 minutes for me to find it and align the scope to it as it was still broad daylight.
Once i got it centred I popped in an eyepiece and the image was terrible, boiling and wriggling about all over the place. Ant V or IV.
Things did not improve much over the hour and it made no difference how fast I ran my (considerable) cooling fans, so I can only conclude that the air above me was churning around a high speed. However the image was sharp despite its constant motion so some details were noted.

The SEB at this longitude is pretty much complete, albeit with a paler patch just rising into view. It is much less red that the NEB, and a little weaker in colour too. The GRS had recently set to the left hand side of the disc.
Callisto is approaching Jupiter for a grazing transit of the SPR.

Wow--nice looking Jupiter. The colors and overall appearance are wonderful. Nice to see the SEB again. Those dark barges must be scattered throughout most of the NEB.

Chris,

An excellent observation of Jupiter. You have recorded much detail across the Jovian disk. The SEB is becoming more prominent whereas the NEB shows much detail as noted. Callisto is a nice addition following the planet. Thank you for sharing it with us all.

Carlos
